Prior versions may result in build failures. Step 1: check out a read only copy of the repository git clone git://github.com/corosync/corosync.git Find the version you want to build. Usually this will be the "master" version. If you want to build a specific released version, use git checkout VERSION. Step 2: Generate the makefiles balance:~/corosync% ./autogen.sh Step 3: Run the configure script balance:~/corosync% ./configure Step 4: Install the binaries balance:~/corosync% su balance:~/corosync# make install ------------------------- * Building from tarball * ------------------------- The tarball is distributed with pregenerated makefiles. There is no need to run the autogen.sh script in this case. Step 1: Run the configure script balance:~/corosync% ./configure Step 2: Install the binaries balance:~/corosync% su balance:~/corosync# make install ------------------------------- * A notice about dependencies * ------------------------------- We have strived very hard to avoid dependencies as much as possible, but there are two required libraries: LibQB and NSS. Optional dependencies are support for Infiniband RDMA, DBUS, SNMP and libstatgrab. The nss packages required to build corosync can usually be found by installing the "nss-devel" and "nspr-devel" packages (names may vary, please use distribution's package manager). Also don't forget to install pkgconfig. ----------------------------------------- * Building with Infiniband RDMA support * ----------------------------------------- Infiniband RDMA build support is disabled by default. To enable rdma during building: balance:~/corosync% ./configure --enable-rdma Infiniband rdma support requires the libibverbs and librdmacm packages (and their -devel counterparts). Corosync requires the use of pkgconfig in these packages. The Corosync maintainers have sent patches for this feature upstream to the Infiniband maintainers. If your version of these packages don't have pkgconfig support, you will see an error during configure such as: checking for ibverbs... configure: error: Package requirements (ibverbs) were not met: No package 'ibverbs' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables ibverbs_CFLAGS and ibverbs_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. ** Follow the directions: balance:~/corosync/trunk% export ibverbs_CFLAGS=-I/usr/include/infiniband balance:~/corosync/trunk% export ibverbs_LIBS=-libverbs balance:~/corosync/trunk% export rdmacm_CFLAGS=-I/usr/include/rdma balance:~/corosync/trunk% export rdmacm_LIBS=-lrdmacm balance:~/corosync/trunk% ./configure --enable-rdma Hopefully pkgconfig support is added in your distribution's version of libibverbs and librdmacm soon if you run into this problem. ----------------------------------------- * Building with SNMP/DBUS support * ----------------------------------------- You can get SNMP traps on the following corosync events: 1) node joine/leave 2) application connect/dissconnect from corosync 3) quorum gain/lost There are 2 modes of achieving this DBUS + foghorn and snmp-agentx. Setting up to get dbus events. ------------------------------ foghorn (http://git.fedorahosted.org/git/foghorn.git) converts dbus signals into snmp traps. So install foghorn. $ ./configure --enable-dbus $ make && sudo make install $ /etc/init.d/corosync start $ echo "OPTIONS=\"-d\"" > /etc/sysconfig/corosync-notifyd $ /etc/init.d/corosync-notifyd start Start foghorn to see the dbus signals getting sent try: $ dbus-monitor --system Setting up snmp-agentx. ----------------------- If you don't want to use dbus then you can use snmp-agentx. $ ./configure --enable-snmp $ make && sudo make install $ /etc/init.d/corosync start $ vim /etc/snmp/snmptrapd.conf Add the following: authCommunity log,execute,net public $ /etc/init.d/snmptrapd start $ echo "OPTIONS=\"-s\"" > /etc/sysconfig/corosync-notifyd $ /etc/init.d/corosync-notifyd start I start up wireshark to see if there are any snmp traps been sent as I am too lazy to setup a manager to receive traps. run a program that talks to corosync e.g. $ corosync-cmapctl And you should get traps ------------------------ * Configuring Corosync * ------------------------ The corosync executive will automatically determine cluster membership by communicating on a specified multicast address and port. The directory conf contains the file corosync.conf.example # Please read the corosync.conf.5 manual page totem { version: 2 secauth: off threads: 0 interface { ringnumber: 0 bindnetaddr: 192.168.1.1 mcastaddr: 226.94.1.1 mcastport: 5405 } } logging { fileline: off to_stderr: yes to_file: yes to_syslog: yes logfile: /tmp/corosync.log debug: off timestamp: on } The totem section contains three values. All three values must be set or the corosync executive wll exit with an error. bindnetaddr specifies the address which the corosync Executive should bind to. This address should always end in zero. If the local interface taffic should routed over is 192.168.5.92, set bindnetaddr to 192.168.5.0. mcastaddr is a multicast address. The default should work but you may have a different network configuration. Avoid 224.x.x.x because this is a "config" multicast address. mcastport specifies the UDP port number. It is possible to use the same multicast address on a network with the corosync services configured for different UDP ports. The timeout section contains seven values. This section is not normally used, but rather used to override the program defaults for the purposes of fine tuning for a given networking/processor combination or for debugging purposes. Be careful to use the same timeout values on each of the nodes in the cluster or unpredictable results may occur. Generate a private key ---------------------- corosync uses cryptographic techniques to ensure authenticity and privacy of messages. A private key must be generated and shared by all processors for correct operation. First generate the key on one of the nodes: balance# corosync-keygen Corosync Authentication key generator. Gathering 1024 bits for key from /dev/random. Writing corosync key to /etc/corosync/authkey. After this is complete, a private key will be in the file /etc/corosync/authkey. This private key must be copied to every processor that will be a member of the cluster. If the private key isn't the same for every node, those nodes with nonmatching private keys will not be able to join the same configuration. Copy the key to some transportable storage or use ssh to transmit the key from node to node. Then install the key with the command: balance# install -D --group=0 --owner=0 --mode=0400 /path_to_authkey/authkey /etc/corosync/authkey If the message invalid digest appears, the keys are not the same on each node. Run the corosync executive ------------------------- Get one or more nodes and run the corosync executive on each node. Run the corosync daemon after following the previous directions. The daemon must be run as UID 0(root). please read SECURITY to understand the threat model assumed by corosync and the techniques corosync use to overcome these threats. Before running any of the test programs --------------------------------------- The corosync executive will ensure security by only allowing the UID 0(root) or GID 0(root) to connect to it. To allow other users to access the corosync executive, create a directory called /etc/corosync/uidgid.d and place a file in it named in some way that is identifiable to you. All files in this directory will be scanned and their contents added to the allowed uid gid database. The contents of this file should be uidgid { uid: username gid: groupname } Please note that these users then have full ability to transmit and receive messages in the cluster and are not bound by the threat model described in SECURITY. Try out the corosync cpg functionality -------------------------------------- After corosync is running Run test/testcpg on multiple nodes or on the same node. Messages can be typed which will then be sent to other testcpg applications in the cluster. To see a hashed verified output of data on all nodes, test/cpgverify can be run. corosync-2.4.3/cts/0000775000076400007640000000000013172367475011202 500000000000000corosync-2.4.3/cts/agents/0000775000076400007640000000000013172367476012464 500000000000000corosync-2.4.3/cts/agents/cpg_test_agent.c0000664000076400007640000005005513172367236015535 00000000000000/* * Copyright (c) 2010 Red Hat, Inc. * * All rights reserved. * * Author: Angus Salkeld (asalkeld@redhat.com) * * This software licensed under BSD license, the text of which follows: * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions are met: * * - Redistributions of source code must retain the above copyright notice, * this list of conditions and the following disclaimer. * - Redistributions in binary form must reproduce the above copyright notice, * this list of conditions and the following disclaimer in the documentation * and/or other materials provided with the distribution. * - Neither the name of the MontaVista Software, Inc. nor the names of its * contributors may be used to endorse or promote products derived from this * software without specific prior written permission. * * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE * ARE DISCLAIMED.

The CTS also uses 2 or more test target nodes(TTN) to run the test cases. The CTS software requires atleast 3 nodes 1 of which acts as a TDN and the remaining acting as TTNs. The dependencies of the TDN include Pacemaker and Augeas. On the single TDN, it is recommended at this time to install pacemaker from source so that the CTS from Pacemaker remains compatible with the current working version of the CTS components within Corosync (currently you will the devel branch http://hg.clusterlabs.org/pacemaker/devel/). 2] ssh access -------------------------------------------------------------------------------- CTS requires login-less root access to the CNs. so if my CN is called "node32" # ssh node32 should not ask for a password and result in a root shell. To enable this behavior, create a ssh key with the command ssh-keygen. When it prompts for a password, enter an empty field. It will create a file called ~/.ssh/id_dsa.pub. Copy that file to the TTNs into /root/.ssh/authorized_keys. Ensure permissions are 700 on /root/.ssh. Test ssh into the machine works without a password from the TDN. 3] Install augeas on the TDN -------------------------------------------------------------------------------- yum install augeas 4] Configuring corosync for CTSs testing -------------------------------------------------------------------------------- ./configure --enable-testagents --enable-augeas --enable-debug and then install it on the TTN. 5] run CTS -------------------------------------------------------------------------------- cd /cts sudo ./corolab.py --nodes "n1 n2 n3" corosync-2.4.3/cts/CTSvars.py.in0000664000076400007640000000013313160753563013415 00000000000000class CTSvars: CTS_home="@prefix@/share/pacemaker/tests/cts" INITDIR="/etc/init.d" corosync-2.4.3/cts/Makefile.in0000664000076400007640000004761013172367461013172 00000000000000# Makefile.in generated by automake 1.11.1 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006, 2007, 2008, 2009 Free Software Foundation, # Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ # Copyright (c) 2010 Red Hat, Inc. # # Authors: Angus Salkeld (asalkeld@redhat.com) # # This software licensed under BSD license, the text of which follows: # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions are met: # # - Redistributions of source code must retain the above copyright notice, # this list of conditions and the following disclaimer. # - Redistributions in binary form must reproduce the above copyright notice, # this list of conditions and the following disclaimer in the documentation # and/or other materials provided with the distribution. # - Neither the name of the MontaVista Software, Inc. nor the names of its # contributors may be used to endorse or promote products derived from this # software without specific prior written permission. # # THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" # AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE # IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE # ARE DISCLAIMED.

(There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.)

There are 4 events of the synchronization algorithm. These events are in fact functions that are registered in the service handler data structure. They are called by the synchronization system whenever a network partitions or merges. init: Within the init event a service handler should record temporary state variables used by the process event. process: The process event is responsible for executing synchronization. This event will return a state as to whether it has completed or not. This allows for synchronization to be interrupted and recontinue when the message queue buffer is full. The process event will be called again by the synchronization service if requesed to do so by the return variable returned in process. abort: The abort event occurs when during synchronization a processor failure occurs. activate: The activate event occurs when process has returned no more processing is necessary for any node in the cluster and all messages originated by process have completed. CHECKPOINT SYNCHRONIZATION ALGORITHM: ------------------------------------ The purpose of the checkpoint syncrhonization algorithm is to synchronize checkpoints after a paritition or merge of two or more partitions. The secondary purpose of the algorithm is to determine the cluster-wide reference count for every checkpoint. Every cluster contains a group of checkpoints. Each checkpoint has a checkpoint name and checkpoint number. The number is used to uniquely reference an unlinked but still open checkpoint in the cluser. Every checkpoint contains a reference count which is used to determine when that checkpoint may be released. The algorithm rebuilds the reference count information each time a partition or merge occurs. local variables my_sync_state may have the values SYNC_CHECKPOINT, SYNC_REFCOUNT my_current_iteration_state contains any data used to iterate the checkpoints and sections. checkpoint data refcount_set contains reference count for every node consisting of number of opened connections to checkpoint and node identifier refcount contains a summation of every reference count in the refcount_set pseudocode executed by a processor when the syncrhonization service calls the init event call process_checkpoints_enter pseudocode executed by a processor when the synchronization service calls the process event in the SYNC_CHECKPOINT state if lowest processor identifier of old ring in new ring transmit checkpoints or sections starting from my_current_iteration_state if all checkpoints and sections could be queued call sync_refcounts_enter else record my_current_iteration_state require process to continue pseudocode executed by a processor when the synchronization service calls the process event in the SYNC_REFCOUNT state if lowest processor identifier of old ring in new ring transmit checkpoint reference counts if all checkpoint reference counts could be queued require process to not continue else record my_current_iteration_state for checkpoint reference counts sync_checkpoints_enter: my_sync_state = SYNC_CHECKPOINT my_current_iteration_state set to start of checkpont list sync_refcounts_enter: my_sync_state = SYNC_REFCOUNT on event receipt of foreign ring id message ignore message pseudocode executed on event receipt of checkpoint update if checkpoint exists in temporary storage ignore message else create checkpoint reset checkpoint refcount array pseudocode executed on event receipt of checkpoint section update if checkpoint section exists in temporary storage ignore message else create checkpoint section pseudocode executed on event receipt of reference count update update temporary checkpoint data storage reference count set by adding any reference counts in the temporary message set to those from the event update that checkpoint's reference count set the global checkpoint id to the current checkpoint id + 1 if it would increase the global checkpoint id pseudocode called when the synchronization service calls the activate event: for all checkpoints free all previously committed checkpoints and sections convert temporary checkpoints and sections to regular sections copy my_saved_ring_id to my_old_ring_id pseudocode called when the synchronization service calls the abort event: free all temporary checkpoints and temporary sections corosync-2.4.3/common_lib/0000775000076400007640000000000013172367475012527 500000000000000corosync-2.4.3/common_lib/Makefile.am0000664000076400007640000000342613160753563014502 00000000000000# # Copyright (c) 2012 Red Hat, Inc. # # Authors: Angus Salkeld # # This software licensed under BSD license, the text of which follows: # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions are met: # # - Redistributions of source code must retain the above copyright notice, # this list of conditions and the following disclaimer. # - Redistributions in binary form must reproduce the above copyright notice, # this list of conditions and the following disclaimer in the documentation # and/or other materials provided with the distribution. # - Neither the name of the MontaVista Software, Inc. nor the names of its # contributors may be used to endorse or promote products derived from this # software without specific prior written permission. # # THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" # AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE # IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE # ARE DISCLAIMED.

The callback function is described by the following type definitions: .nf typedef void (*votequorum_nodelist_notification_fn_t) ( votequorum_handle_t handle, uint64_t context, uint32_t node_list_entries, uint32_t node_list[] ); .fi Current ring_id (one get in votequorum_quorum_notification_fn) must be passed to .B votequorum_qdevice_poll to make qdevice voting valid. .PP Every time the quorum state changes (eg a node joins or leave the cluster), the callback is called. The callback function is described by the following type definitions: .nf typedef void (*votequorum_quorum_notification_fn_t) ( votequorum_handle_t handle, uint64_t context, uint32_t quorate, uint32_t node_list_entries, votequorum_node_t node_list[] ); .fi The difference between votequorum_nodelist_notification_t and votequorum_quorum_notification_t is subtle but important. The 'nodelist' callback is sent at the start of a cluster state transition and contains the new ring_id and only the list of nodes that are included in the sync state - ie only active nodes. No quorum information is included this callback because it is not available at that time. The 'quorum' callback is sent after the cluster state transition has completed and does contain quorum information. In addition, the nodelist contains a list of all nodes known to votequorum (whether up or down) and their state as well as information about the quorum device attached (if any). Quorum callbacks will not be sent for qdevice up and down events unless they affect quorum. .PP Every time the expected votes are changed, the callback is called. The expected votes callback function is described by the following type definitions: .nf typedef void (*votequorum_expectedvotes_notification_fn_t) ( votequorum_handle_t handle, uint64_t context, uint32_t expected_votes); .fi .PP The .I callbacks argument is of the type: .nf typedef struct { votequorum_quorum_notification_fn_t votequorum_quorum_notify_fn; votequorum_expectedvotes_notification_fn_t votequorum_expectedvotes_notify_fn; votequorum_nodelist_notification_fn_t votequorum_nodelist_notify_fn; } votequorum_callbacks_t; .fi .PP When a configuration change occurs, the callback is called from the .B votequorum_dispatch() function. .PP .SH RETURN VALUE This call returns the CS_OK value if successful, otherwise an error is returned. .SH ERRORS @COMMONIPCERRORS@ .SH "SEE ALSO" .BR votequorum_overview (8), .BR votequorum_finalize (3), .BR votequorum_getinfo (3), .BR votequorum_trackstart (3), .BR votequorum_trackstop (3), .BR votequorum_fd_get (3), .BR votequorum_dispatch (3), .BR votequorum_context_set (3), .BR votequorum_context_get (3), .BR votequorum_setexpected (3), .BR votequorum_setvotes (3) .PP corosync-2.4.3/man/cmap_overview.80000664000076400007640000000525013172367236014040 00000000000000.\"/* .\" * Copyright (c) 2012 Red Hat, Inc. .\" * .\" * All rights reserved. .\" * .\" * Author: Jan Friesse (jfriesse@redhat.com) .\" * .\" * This software licensed under BSD license, the text of which follows: .\" * .\" * Redistribution and use in source and binary forms, with or without .\" * modification, are permitted provided that the following conditions are met: .\" * .\" * - Redistributions of source code must retain the above copyright notice, .\" * this list of conditions and the following disclaimer. .\" * - Redistributions in binary form must reproduce the above copyright notice, .\" * this list of conditions and the following disclaimer in the documentation .\" * and/or other materials provided with the distribution. .\" * - Neither the name of the Red Hat, Inc. nor the names of its .\" * contributors may be used to endorse or promote products derived from this .\" * software without specific prior written permission. .\" * .\" * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" .\" * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE .\" * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE .\" * ARE DISCLAIMED.

It is the external interface to the vote-based quorum service. This service is optionally loaded into all nodes in a corosync cluster to avoid split-brain situations. It does this by having a number of votes assigned to each system in the cluster and ensuring that only when a majority of the votes are present, cluster operations are allowed to proceed. .PP The library provides a mechanism to: .PP * Query the quorum status .PP * Get a list of nodes known to the quorum service .PP * Receive notifications of quorum state changes .PP * Change the number of votes assigned to a node .PP * Change the number of expected votes for a cluster to be quorate .PP * Connect an additional quorum device to allow small clusters to remain quorate during node outages. .PP .SH VIRTUAL SYNCHRONY Votequorum is the only one service where communication with library is allowed during synchronization phase. This makes it possible for quorum device to react to membership change and decide to vote or not without timing hazard, because corosync stands in synchronization phase until qdevice on all nodes votes or timeout expires. As a side effect, extended virtual synchrony is broken for the votequorum service. This means, that messages sent during synchronization phase can be delivered sooner then messages sent right before sync phase began. This applies also for local messages. .SH BUGS No known bugs at the time of writing. The authors are from outerspace.

One CMAP connection can track multiple keys and also it's possible to track one key multiple times. The .I handle argument is connection to CMAP database obtained by calling .B cmap_initialize(3) function. .I key_name argument is ether exact key name or prefix of key name to track changes on. .I track_type is bitfield which may consist of following values: .PP \fBCMAP_TRACK_ADD\fR - track addition of new key (or key added in callback) .PP \fBCMAP_TRACK_DELETE\fR - track deletion of key (or key deleted in callback) .PP \fBCMAP_TRACK_MODIFY\fR - track modification of key (or key modified in callback) .PP \fBCMAP_TRACK_PREFIX\fR - whole prefix is tracked, instead of key only, so "totem." tracking means that "totem.nodeid", "totem.version", ... applies (this value is never returned in callback) .PP .I notify_fn is pointer to function which is called when value is changed. It's definition and meaning of parameters is discussed below. .I user_data argument is passed directly to .I notify_fn without any changes. .I cmap_track_handle is used for removing of tracking when no longer needed by calling .B cmap_track_delete(3) function. Callback function is defined as: .IP .RS .ne 18 .nf .PP typedef void (*cmap_notify_fn_t) ( cmap_handle_t cmap_handle, cmap_track_handle_t cmap_track_handle, int32_t event, const char *key_name, struct cmap_notify_value new_value, struct cmap_notify_value old_value, void *user_data); .ta .fi .RE .IP .PP where .I cmap_handle is handle used in registration of track function. .I cmap_track_handle is handle returned by .B cmap_track_add function. .I event is one of \fBCMAP_TRACK_ADD\fR, \fBCMAP_TRACK_DELETE\fR or \fBCMAP_TRACK_MODIFY\fR. .I key_name is name of changed key. .I new_value is new value of key, or unset if .I event is \fBCMAP_TRACK_DELETE\fR. .I old_value is previous value of key or unset if .I event is \fBCMAP_TRACK_ADD\fR or for some special keys set directly by Corosync due to speed optimizations. Both .I new_value and .I old_value are structures defined as: .IP .RS .ne 18 .nf .PP struct cmap_notify_value { cmap_value_types_t type; size_t len; const void *data; }; .ta .fi .RE .IP .PP If value is unset, all fields are set to 0. Otherwise .I type is one of cmap types (as described in .B cmap_get(3) function), .I len is length of value in cmap and .I data is pointer to value of item.

Empty lines and lines starting with # character are ignored. The configuration file consists of bracketed top level directives. The possible directive choices are: .TP totem { } This top level directive contains configuration options for the totem protocol. .TP logging { } This top level directive contains configuration options for logging. .TP quorum { } This top level directive contains configuration options for quorum. .TP nodelist { } This top level directive contains configuration options for nodes in cluster. .TP qb { } This top level directive contains configuration options related to libqb. .TP resources { } This top level directive contains configuration options for resources. .PP .PP Within the .B totem directive, an interface directive is required. There is also one configuration option which is required: .PP .PP Within the .B interface sub-directive of totem there are four parameters which are required. There is one parameter which is optional. .TP ringnumber This specifies the ring number for the interface. When using the redundant ring protocol, each interface should specify separate ring numbers to uniquely identify to the membership protocol which interface to use for which redundant ring. The ringnumber must start at 0. .TP bindnetaddr This specifies the network address the corosync executive should bind to. bindnetaddr should be an IP address configured on the system, or a network address. For example, if the local interface is 192.168.5.92 with netmask 255.255.255.0, you should set bindnetaddr to 192.168.5.92 or 192.168.5.0. If the local interface is 192.168.5.92 with netmask 255.255.255.192, set bindnetaddr to 192.168.5.92 or 192.168.5.64, and so forth. This may also be an IPV6 address, in which case IPV6 networking will be used. In this case, the exact address must be specified and there is no automatic selection of the network interface within a specific subnet as with IPv4. If IPv6 networking is used, the nodeid field in nodelist must be specified. .TP broadcast This is optional and can be set to yes. If it is set to yes, the broadcast address will be used for communication. If this option is set, mcastaddr should not be set. .TP mcastaddr This is the multicast address used by corosync executive. The default should work for most networks, but the network administrator should be queried about a multicast address to use. Avoid 224.x.x.x because this is a "config" multicast address. This may also be an IPV6 multicast address, in which case IPV6 networking will be used. If IPv6 networking is used, the nodeid field in nodelist must be specified. It's not needed to use this option if cluster_name option is used. If both options are used, mcastaddr has higher priority. .TP mcastport This specifies the UDP port number. It is possible to use the same multicast address on a network with the corosync services configured for different UDP ports. Please note corosync uses two UDP ports mcastport (for mcast receives) and mcastport - 1 (for mcast sends). If you have multiple clusters on the same network using the same mcastaddr please configure the mcastports with a gap. .TP ttl This specifies the Time To Live (TTL). If you run your cluster on a routed network then the default of "1" will be too small. This option provides a way to increase this up to 255. The valid range is 0..255. Note that this is only valid on multicast transport types. .PP .PP Within the .B totem directive, there are seven configuration options of which one is required, five are optional, and one is required when IPV6 is configured in the interface subdirective. The required directive controls the version of the totem configuration. The optional option unless using IPV6 directive controls identification of the processor. The optional options control secrecy and authentication, the redundant ring mode of operation and maximum network MTU field. .TP version This specifies the version of the configuration file. Currently the only valid version for this directive is 2. .PP clear_node_high_bit This configuration option is optional and is only relevant when no nodeid is specified. Some corosync clients require a signed 32 bit nodeid that is greater than zero however by default corosync uses all 32 bits of the IPv4 address space when generating a nodeid. Set this option to yes to force the high bit to be zero and therefor ensure the nodeid is a positive signed 32 bit integer. WARNING: The clusters behavior is undefined if this option is enabled on only a subset of the cluster (for example during a rolling upgrade). .TP crypto_hash This specifies which HMAC authentication should be used to authenticate all messages. Valid values are none (no authentication), md5, sha1, sha256, sha384 and sha512. The default is sha1. .TP crypto_cipher This specifies which cipher should be used to encrypt all messages. Valid values are none (no encryption), aes256, aes192, aes128 and 3des. Enabling crypto_cipher, requires also enabling of crypto_hash. The default is aes256. .TP secauth This specifies that HMAC/SHA1 authentication should be used to authenticate all messages. It further specifies that all data should be encrypted with the nss library and aes256 encryption algorithm to protect data from eavesdropping. Enabling this option adds a encryption header to every message sent by totem which reduces total throughput. Also encryption and authentication consume extra CPU cycles in corosync. The default is on. WARNING: This parameter is deprecated. It's recomended to use combination of crypto_cipher and crypto_hash. .TP rrp_mode This specifies the mode of redundant ring, which may be none, active, or passive. Currently only 'passive' is supported or tested (using 'active' is not recommended). Active replication offers slightly lower latency from transmit to delivery in faulty network environments but with less performance. Passive replication may nearly double the speed of the totem protocol if the protocol doesn't become cpu bound. The final option is none, in which case only one network interface will be used to operate the totem protocol. If only one interface directive is specified, none is automatically chosen. If multiple interface directives are specified, only active or passive may be chosen. The maximum number of interface directives that is allowed for either modes (active or passive) is 2. When using multiple interfaces, make sure to use different multicast address/port (port for same address must differ by at least two) pair for each interface (this is checked by parser) to make rrp works. .TP netmtu This specifies the network maximum transmit unit. To set this value beyond 1500, the regular frame MTU, requires ethernet devices that support large, or also called jumbo, frames. If any device in the network doesn't support large frames, the protocol will not operate properly. The hosts must also have their mtu size set from 1500 to whatever frame size is specified here. Please note while some NICs or switches claim large frame support, they support 9000 MTU as the maximum frame size including the IP header. Setting the netmtu and host MTUs to 9000 will cause totem to use the full 9000 bytes of the frame. Then Linux will add a 18 byte header moving the full frame size to 9018. As a result some hardware will not operate properly with this size of data. A netmtu of 8982 seems to work for the few large frame devices that have been tested. Some manufacturers claim large frame support when in fact they support frame sizes of 4500 bytes. When sending multicast traffic, if the network frequently reconfigures, chances are that some device in the network doesn't support large frames. Choose hardware carefully if intending to use large frame support. The default is 1500. .TP transport This directive controls the transport mechanism used. If the interface to which corosync is binding is an RDMA interface such as RoCEE or Infiniband, the "iba" parameter may be specified. To avoid the use of multicast entirely, a unicast transport parameter "udpu" can be specified. This requires specifying the list of members in nodelist directive, that could potentially make up the membership before deployment. The default is udp. The transport type can also be set to udpu or iba. .TP cluster_name This specifies the name of cluster and it's used for automatic generating of multicast address. .TP config_version This specifies version of config file. This is converted to unsigned 64-bit int. By default it's 0. Option is used to prevent joining old nodes with not up-to-date configuration. If value is not 0, and node is going for first time (only for first time, join after split doesn't follow this rules) from single-node membership to multiple nodes membership, other nodes config_versions are collected. If current node config_version is not equal to highest of collected versions, corosync is terminated. .TP ip_version Specifies version of IP to use for communication. Value can be one of ipv4 or ipv6. Default (if unspecified) is ipv4. Within the .B totem directive, there are several configuration options which are used to control the operation of the protocol. It is generally not recommended to change any of these values without proper guidance and sufficient testing. Some networks may require larger values if suffering from frequent reconfigurations. Some applications may require faster failure detection times which can be achieved by reducing the token timeout. .TP token This timeout is used directly or as a base for real token timeout calculation (explained in .B token_coefficient section). Token timeout specifies in milliseconds until a token loss is declared after not receiving a token. This is the time spent detecting a failure of a processor in the current configuration. Reforming a new configuration takes about 50 milliseconds in addition to this timeout. For real token timeout used by totem it's possible to read cmap value of .B runtime.config.token key. The default is 1000 milliseconds. .TP token_coefficient This value is used only when .B nodelist section is specified and contains at least 3 nodes. If so, real token timeout is then computed as token + (number_of_nodes - 2) * token_coefficient. This allows cluster to scale without manually changing token timeout every time new node is added. This value can be set to 0 resulting in effective removal of this feature. The default is 650 milliseconds. .TP token_retransmit This timeout specifies in milliseconds after how long before receiving a token the token is retransmitted. This will be automatically calculated if token is modified. It is not recommended to alter this value without guidance from the corosync community. The default is 238 milliseconds. .TP hold This timeout specifies in milliseconds how long the token should be held by the representative when the protocol is under low utilization. It is not recommended to alter this value without guidance from the corosync community. The default is 180 milliseconds. .TP token_retransmits_before_loss_const This value identifies how many token retransmits should be attempted before forming a new configuration. If this value is set, retransmit and hold will be automatically calculated from retransmits_before_loss and token. The default is 4 retransmissions. .TP join This timeout specifies in milliseconds how long to wait for join messages in the membership protocol. The default is 50 milliseconds. .TP send_join This timeout specifies in milliseconds an upper range between 0 and send_join to wait before sending a join message. For configurations with less than 32 nodes, this parameter is not necessary. For larger rings, this parameter is necessary to ensure the NIC is not overflowed with join messages on formation of a new ring. A reasonable value for large rings (128 nodes) would be 80msec. Other timer values must also change if this value is changed. Seek advice from the corosync mailing list if trying to run larger configurations. The default is 0 milliseconds. .TP consensus This timeout specifies in milliseconds how long to wait for consensus to be achieved before starting a new round of membership configuration. The minimum value for consensus must be 1.2 * token. This value will be automatically calculated at 1.2 * token if the user doesn't specify a consensus value. For two node clusters, a consensus larger than the join timeout but less than token is safe. For three node or larger clusters, consensus should be larger than token. There is an increasing risk of odd membership changes, which still guarantee virtual synchrony, as node count grows if consensus is less than token. The default is 1200 milliseconds. .TP merge This timeout specifies in milliseconds how long to wait before checking for a partition when no multicast traffic is being sent. If multicast traffic is being sent, the merge detection happens automatically as a function of the protocol. The default is 200 milliseconds. .TP downcheck This timeout specifies in milliseconds how long to wait before checking that a network interface is back up after it has been downed. The default is 1000 milliseconds. .TP fail_recv_const This constant specifies how many rotations of the token without receiving any of the messages when messages should be received may occur before a new configuration is formed. The default is 2500 failures to receive a message. .TP seqno_unchanged_const This constant specifies how many rotations of the token without any multicast traffic should occur before the hold timer is started. The default is 30 rotations. .TP heartbeat_failures_allowed [HeartBeating mechanism] Configures the optional HeartBeating mechanism for faster failure detection. Keep in mind that engaging this mechanism in lossy networks could cause faulty loss declaration as the mechanism relies on the network for heartbeating. So as a rule of thumb use this mechanism if you require improved failure in low to medium utilized networks. This constant specifies the number of heartbeat failures the system should tolerate before declaring heartbeat failure e.g 3. Also if this value is not set or is 0 then the heartbeat mechanism is not engaged in the system and token rotation is the method of failure detection The default is 0 (disabled). .TP max_network_delay [HeartBeating mechanism] This constant specifies in milliseconds the approximate delay that your network takes to transport one packet from one machine to another. This value is to be set by system engineers and please don't change if not sure as this effects the failure detection mechanism using heartbeat. The default is 50 milliseconds. .TP window_size This constant specifies the maximum number of messages that may be sent on one token rotation. If all processors perform equally well, this value could be large (300), which would introduce higher latency from origination to delivery for very large rings. To reduce latency in large rings(16+), the defaults are a safe compromise. If 1 or more slow processor(s) are present among fast processors, window_size should be no larger than 256000 / netmtu to avoid overflow of the kernel receive buffers. The user is notified of this by the display of a retransmit list in the notification logs. There is no loss of data, but performance is reduced when these errors occur. The default is 50 messages. .TP max_messages This constant specifies the maximum number of messages that may be sent by one processor on receipt of the token. The max_messages parameter is limited to 256000 / netmtu to prevent overflow of the kernel transmit buffers. The default is 17 messages. .TP miss_count_const This constant defines the maximum number of times on receipt of a token a message is checked for retransmission before a retransmission occurs. This parameter is useful to modify for switches that delay multicast packets compared to unicast packets. The default setting works well for nearly all modern switches. The default is 5 messages. .TP rrp_problem_count_timeout This specifies the time in milliseconds to wait before decrementing the problem count by 1 for a particular ring to ensure a link is not marked faulty for transient network failures. The default is 2000 milliseconds. .TP rrp_problem_count_threshold This specifies the number of times a problem is detected with a link before setting the link faulty. Once a link is set faulty, no more data is transmitted upon it. Also, the problem counter is no longer decremented when the problem count timeout expires. A problem is detected whenever all tokens from the proceeding processor have not been received within the rrp_token_expired_timeout. The rrp_problem_count_threshold * rrp_token_expired_timeout should be atleast 50 milliseconds less then the token timeout, or a complete reconfiguration may occur. The default is 10 problem counts. .TP rrp_problem_count_mcast_threshold This specifies the number of times a problem is detected with multicast before setting the link faulty for passive rrp mode. This variable is unused in active rrp mode. The default is 10 times rrp_problem_count_threshold. .TP rrp_token_expired_timeout This specifies the time in milliseconds to increment the problem counter for the redundant ring protocol after not having received a token from all rings for a particular processor. This value will automatically be calculated from the token timeout and problem_count_threshold but may be overridden. It is not recommended to override this value without guidance from the corosync community. The default is 47 milliseconds. .TP rrp_autorecovery_check_timeout This specifies the time in milliseconds to check if the failed ring can be auto-recovered. The default is 1000 milliseconds. .PP Within the .B logging directive, there are several configuration options which are all optional. .PP The following 3 options are valid only for the top level logging directive: .TP timestamp This specifies that a timestamp is placed on all log messages. The default is off. .TP fileline This specifies that file and line should be printed. The default is off. .TP function_name This specifies that the code function name should be printed. The default is off. .PP The following options are valid both for top level logging directive and they can be overridden in logger_subsys entries. .TP to_stderr .TP to_logfile .TP to_syslog These specify the destination of logging output. Any combination of these options may be specified. Valid options are .B yes and .B no. The default is syslog and stderr. Please note, if you are using to_logfile and want to rotate the file, use logrotate(8) with the option .B copytruncate. eg. .ne 18 .RS .nf .ft CW /var/log/corosync.log { missingok compress notifempty daily rotate 7 copytruncate } .ft .fi .RE .TP logfile If the .B to_logfile directive is set to .B yes , this option specifies the pathname of the log file. No default. .TP logfile_priority This specifies the logfile priority for this particular subsystem. Ignored if debug is on. Possible values are: alert, crit, debug (same as debug = on), emerg, err, info, notice, warning. The default is: info. .TP syslog_facility This specifies the syslog facility type that will be used for any messages sent to syslog. options are daemon, local0, local1, local2, local3, local4, local5, local6 & local7. The default is daemon. .TP syslog_priority This specifies the syslog level for this particular subsystem. Ignored if debug is on. Possible values are: alert, crit, debug (same as debug = on), emerg, err, info, notice, warning. The default is: info. .TP debug This specifies whether debug output is logged for this particular logger. Also can contain value trace, what is highest level of debug information. The default is off. .PP Within the .B logging directive, logger_subsys directives are optional. .PP Within the .B logger_subsys sub-directive, all of the above logging configuration options are valid and can be used to override the default settings. The subsys entry, described below, is mandatory to identify the subsystem. .TP subsys This specifies the subsystem identity (name) for which logging is specified. This is the name used by a service in the log_init() call. E.g. 'CPG'. This directive is required. .PP Within the .B quorum directive it is possible to specify the quorum algorithm to use with the .TP provider directive. At the time of writing only corosync_votequorum is supported. See votequorum(5) for configuration options. .PP Within the .B nodelist directive it is possible to specify specific information about nodes in cluster. Directive can contain only .B node sub-directive, which specifies every node that should be a member of the membership, and where non-default options are needed. Every node must have at least ring0_addr field filled. For UDPU, every node that should be a member of the membership must be specified. Possible options are: .TP ringX_addr This specifies IP address of one of the nodes. X is ring number. .TP nodeid This configuration option is optional when using IPv4 and required when using IPv6. This is a 32 bit value specifying the node identifier delivered to the cluster membership service. If this is not specified with IPv4, the node id will be determined from the 32 bit IP address the system to which the system is bound with ring identifier of 0. The node identifier value of zero is reserved and should not be used. .PP Within the .B qb directive it is possible to specify options for libqb. Possible option is: .TP ipc_type This specifies type of IPC to use. Can be one of native (default), shm and socket. Native means one of shm or socket, depending on what is supported by OS. On systems with support for both, SHM is selected. SHM is generally faster, but need to allocate ring buffer file in /dev/shm. .PP Within the .B resources directive it is possible to specify options for resources. Possible option is: .TP watchdog_device (Valid only if Corosync was compiled with watchdog support.) .br Watchdog device to use. The default value is /dev/watchdog. The special value "off" disables watchdog usage. .IP In a cluster with properly configured power fencing a watchdog provides no additional value. On the other hand, slow watchdog communication may incur multi-second delays in the Corosync main loop, potentially breaking down membership. IPMI watchdogs are particularly notorious in this regard: read about kipmid_max_busy_us in IPMI.txt in the Linux kernel documentation. .SH "FILES" .TP /etc/corosync/corosync.conf The corosync executive configuration file. .SH "SEE ALSO" .BR corosync_overview (8), .BR votequorum (5), .BR corosync-qdevice (8), .BR logrotate (8) .PP corosync-2.4.3/man/corosync-qdevice.80000664000076400007640000003423513172367263014454 00000000000000.\"/* .\" * Copyright (C) 2016-2017 Red Hat, Inc. .\" * .\" * All rights reserved. .\" * .\" * Author: Jan Friesse .\" * .\" * This software licensed under BSD license, the text of which follows: .\" * .\" * Redistribution and use in source and binary forms, with or without .\" * modification, are permitted provided that the following conditions are met: .\" * .\" * - Redistributions of source code must retain the above copyright notice, .\" * this list of conditions and the following disclaimer. .\" * - Redistributions in binary form must reproduce the above copyright notice, .\" * this list of conditions and the following disclaimer in the documentation .\" * and/or other materials provided with the distribution. .\" * - Neither the name of Red Hat, Inc. nor the names of its .\" * contributors may be used to endorse or promote products derived from this .\" * software without specific prior written permission. .\" * .\" * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" .\" * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE .\" * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE .\" * ARE DISCLAIMED.

It provides a configured number of votes to the quorum subsystem based on a third-party arbitrator's decision. Its primary use is to allow a cluster to sustain more node failures than standard quorum rules allow. It is recommended for clusters with an even number of nodes and highly recommended for 2 node clusters. .SH OPTIONS .TP .B -d Forcefully turn on debug information without the need to change corosync.conf. .TP .B -f Do not daemonize, run in the foreground. .TP .B -h Show short help text .TP .B -S Set advanced settings described in its own section below. This option shouldn't be generally used because most of the options are not safe to change. .SH CONFIGURATION .B corosync-qdevice reads its configuration from corosync.conf file. The main configuration is within .B quorum.device sub-key. Each model also has its own configuration within a similarly named sub-key. .TP .B model Specifies the model to be used. This parameter is required. .B corosync-qdevice is modular and is able to support multiple different models. The model basically defines what type of arbitrator is used. Currently only .I net is supported. .TP .B timeout Specifies how often .B corosync-qdevice should call the votequorum_poll function. It is also used by the net model to adjust its hearbeat timeout. It is recommended that you don't change this value. Default is 10000. .TP .B sync_timeout Specifies how often .B corosync-qdevice should call the votequorum_poll function during a sync phase. It is recommended that you don't change this value. Default is 30000. .TP .B votes The number of votes provided to the cluster by qdevice. Default is (number_of_nodes - 1) or generally sum(votes_per_node) - 1. .PP .B quorum.device.heuristics subkey holds the configuration of the heuristics. Heuristics are set of commands executed locally on startup, cluster membership change, successful connect to .B corosync-qnetd and optionally also at regular times. When all commands finish successfully (their return error code is zero) on time, heuristics have passed, otherwise they have failed. The heuristics result is sent to .B corosync-qnetd and there it's used in calculations to determine which partition should be quorate. .TP .B timeout Specifies maximum time in milliseconds how long .B corosync-qdevice waits till the heuristics commands finish. If some command doesn't finish before the timeout, it's killed and heuristics fail. This timeout is used for heuristics executed at regular times. Default value is half of the quorum.device.timeout, so 5000. .TP .B sync_timeout Similar to quorum.device.heuristics.timeout but used during membership changes. Default value is half of the quorum.device.sync_timeout, so 15000. .TP .B interval Specifies interval between two regular heuristics execution. Default value is 3 * quorum.device.timeout, so 30000. .TP .B mode Can be on of .I on, sync or off and specifies mode of operation of heuristics. Default is .I off what means heuristics are disabled. When .I sync is set, heuristics are executed only during startup, membership change and when connection to .B corosync-qnetd is established. When heuristics should be running also on regular basis, this option should be set to .I on value. .TP .B exec_NAME defines executables. .I NAME can be arbitrary valid cmap key name string and it has no special meaning. The value of this variable must contain a command to execute. The alue is parsed (split) into arguments similarly as Bourne shell would do. Quoting is possible by using backslash and double quotes. .PP .B quorum.device.net subkey holds the configuration for model 'net'. .TP .B tls Can be one of .I on, off or required and specifies if tls should be used. .I on means a connection with TLS is attempted first, but if the server doesn't advertise TLS support then non-TLS will be used. .I off is used then TLS is not required and it's then not even tried. This mode is the only one which doesn't need a properly initialized NSS database. .I required means TLS is required and if the server doesn't support TLS, qdevice will exit with error message. Default is on. .TP .B host Specifies the IP address or host name of the qnetd server to be used. This parameter is required. .TP .B port Specifies TCP port of qnetd server. Default is 5403. .TP .B algorithm Decision algorithm. Can be one of the .I ffsplit or .I lms. (actually there are also .I test and .I 2nodelms , both of which are mainly for developers and shouldn't be used for production clusters). For a description of what each algorithm means and how the algorithms differ see their individual sections. Default value is ffsplit. .TP .B tie_breaker can be one of .I lowest, .I highest or valid_node_id (number) values. It's used as a fallback if qdevice has to decide between two or more equal partitions. .I lowest means the partition with the lowest node id is chosen. .I highest means the partition with highest node id is chosen. And valid_node_id means that the partition containing the node with the given node id is chosen. Default is 'lowest'. .TP .B connect_timeout Timeout when .B corosync-qdevice is trying to connect to .B corosync-qnetd host. Default is 0.8 * quorum.sync_timeout. .TP .B force_ip_version can be one of .I 0|4|6 and forces the software to use the given IP version. .I 0 (default value) means IPv6 is prefered and IPv4 should be used as a fallback. .PP Logging configuration is within the .B logging directive. .B corosync-qdevice parses and supports most of the options with exception of .B to_logfile, .B logfile and .B logfile_priority. The .B logger_subsys sub-directive can be also used if .B subsys is set to QDEVICE. .PP For .B corosync-qdevice to work correctly, the .B nodelist directive has to be used and properly configured. Also the net model requires that .B totem.cluster_name option is set. .SH MODEL NET TLS CONFIGURATION For model net to work using TLS, it's necessary to create the NSS database, import Qnetd CA certificate, and get/distribute a valid client certificate. If pcs is used (recommended) the following steps are not needed because pcs does them automatically. .B corosync-qdevice-net-certutil is the tool to perform required actions semi-automatically. Please consult the help output of it and its man page. For a first time configuration it may make sense to start with the .B -Q option. If TLS is not required just edit corosync.conf file and set .B quorum.device.net.tls to .I off. .SH MODEL NET ALGORITHMS Algorithms are used to change behavior of how .B corosync-qnetd provides votes to a given node/partition. Currently there are two algorithms supported. .TP .B ffsplit This one makes sense only for clusters with an even number of nodes. It provides exactly one vote to the partition with the highest number of active nodes. If there are two exactly similar partitions, it provides its vote to the partition with higher score. The score is computed as (number_of_connected_nodes + number_of_connected_nodes_with_passed_heuristics - number_of_connected_nodes_with_failed_heuristics) If the scores are equal, the vote is provided to partition with the most clients connected to the qnetd server. If this number is also equal, then the tie_breaker is used. It is able to transition its vote if the currently active partition becomes partitioned and a non-active partition still has at least 50% of the active nodes. Because of this, a vote is not provided if the qnetd connection is not active. To use this algorithm it's required to set the number of votes per node to 1 (default) and the qdevice number of votes has to be also 1. This is achieved by setting .B quorum.device.votes key in corosync.conf file to 1. .TP .B lms Last-man-standing. If the node is the only one left in the cluster that can see the qnetd server then we return a vote. If more than one node can see the qnetd server but some nodes can't see each other then the cluster is divided up into 'partitions' based on their ring_id and this algorithm returns a vote to the partition with highest heuristics score (computed the same way as for the .B ffsplit algorithm), or if there is more than 1 partition with equal scores, the largest active partition or, if there is more than 1 equal partition, the partition that contains the tie_breaker node (lowest, highest, etc). For LMS to work, the number of qdevice votes has to be set to default (so just delete .B quorum.device.votes key from corosync.conf). .SH ADVANCED SETTINGS Set by using .B -S option. The default value is shown in parentheses) Options beginning with .B net_ prefix are specific to model net. .TP .B lock_file Lock file location.

Each application uses the .I handle argument to uniquely identify the connection. .PP The .I dispatch_types argument is used to identify the type of dispatch to execute.

In this man page, wild-cards have the usual meaning. .SH KEYS .TP internal_configuration.* Internal configuration data. All keys in this prefix are read only. It's only useful for getting a list of loaded services. .TP logging.* Values read from the configuration file. It's possible to change them at runtime. If subsystem specific configuration is needed, the key must be in the form logging.logger_subsys.SERVICE.key, where SERVICE is upper case name of the service and key is same as in the configuration file. All values are of string type. .TP nodelist.* Values read from the configuration file. Each node element in the configuration file gets assigned it's position starting from zero. So the first node from the config file has nodelist.node.0. prefix. To be a valid entry, each node must have .B ring0_addr key. To change the .B nodeid key, use a u32 data type. Local node position is stored in .B local_node_pos key (RO), so it's easy to find out nodeid/ring addresses of the local node directly from cmap. .TP runtime.blackbox.* Trigger keys for storing fplay data. It's recommended that you the corosync-blackbox command to change keys in this prefix. .TP runtime.connections.* There is information about total number of active connections in given moment in the .B active key, number of closed connections during whole runtime of corosync in the .B closed key and information about each active IPC connection. All keys in this prefix are read-only. .TP runtime.connections.ID.* Each IPC connection has a unique ID. This is in the form [[short_name:][PID:]internal_id. On some platforms, short_name and PID are not filled and only internal_id is used. Typical keys in this prefix are: .B client_pid containing PID of IPC connection (unavailable on some platforms). .B dispatched number of dispatched messages. .B invalid_request number of requests made by IPC which are invalid (calling non-existing call, ...). .B name contains short name of the IPC connection (unavailable on some platforms). .B overload is number of requests which were not processed because of overload. .B queue_size contains the number of messages in the queue waiting for send. .B recv_retries is the total number of interrupted receives. .B requests contains the number of requests made by IPC. .B responses is the number of responses sent to the IPC client. .B send_retries contains the total number of interrupted sends. .B service_id contains the ID of service which the IPC is connected to. .TP runtime.config.* Contains the values actually in use by the totem membership protocol. Values here are either taken from the Corosync configuration file, defaults or computed from entries in the config file. For information on individual keys please refer to the man page .BR corosync.conf (5). .TP runtime.services.* Prefix with statistics for service engines. Each service has it's own .B service_id key in the prefix with the name runtime.services.SERVICE., where SERVICE is the lower case name of the service. Inside the service prefix is the number of messages received and sent by the corosync engine in the format runtime.services.SERVICE.EXEC_CALL.rx and runtime.services.SERVICE.EXEC_CALL.tx, where EXEC_CALL is the internal id of the service call (so for example 3 in cpg service is receive of multicast message from other nodes). .TP runtime.totem.pg.mrp.srp.* Prefix containing statistics about totem. All keys here are read only. Typical key prefixes: .B commit_entered Number of times the processor entered COMMIT state. .B commit_token_lost Number of times the processor lost token in COMMIT state. .B consensus_timeouts How many times the processor timed out forming a consensus about membership. .B continuous_gather How many times the processor was not able to reach consensus. .B firewall_enabled_or_nic_failure Set to 1 when processor was not able to reach consensus for long time. The usual reason is a badly configured firewall or connection failure. .B gather_entered Number of times the processor entered GATHER state. .B gather_token_lost Number of times the processor lost token in GATHER state. .B mcast_retx Number of retransmitted messages. .B mcast_rx Number of received multicast messages. .B mcast_tx Number of transmitted multicast messages. .B memb_commit_token_rx Number of received commit tokens. .B memb_commit_token_tx Number of transmitted commit tokens. .B memb_join_rx Number of received join messages. .B memb_join_tx Number of transmitted join messages. .B memb_merge_detect_rx Number of received member merge messages. .B memb_merge_detect_tx Number of transmitted member merge messages. .B orf_token_rx Number of received orf tokens. .B orf_token_tx Number of transmitted orf tokens. .B recovery_entered Number of times the processor entered recovery. .B recovery_token_lost Number of times the token was lost in recovery state. .B rx_msg_dropped Number of received messages which were dropped because they were not expected (as example multicast message in commit state). .B token_hold_cancel_rx Number of received token hold cancel messages. .B token_hold_cancel_tx Number of transmitted token hold cancel messages. .B mtt_rx_token Mean transit time of token in milliseconds. In other words, time between two consecutive token receives. .B avg_token_workload Average time in milliseconds of holding time of token on the current processor. .B avg_backlog_calc Average number of not yet sent messages on the current processor. .TP runtime.totem.pg.mrp.srp.members.* Prefix containing members of the totem single ring protocol. Each member keys has format runtime.totem.pg.mrp.srp.members.NODEID.KEY, where key is one of: .B ip IP address of member. It's stored in format r(RING_ID) ip(IP_ADDRESS). .B join_count Number of times the processor joined membership with local cluster. When processor fails and rejoins again, this value is incremented. .B status Status of the processor. Can be one of joined and left. .B config_version Config version of the member node. .TP resources.process.PID.* Prefix created by applications using SAM with CMAP integration. It contains the following keys: .B recovery Recovery policy of the process. Can be one of quit or restart. .B poll_period Value passed in sam_initialize as a time_interval. .B last_updated Last time SAM received a heartbeat from the client. .B state State of the client. Can be one of failed, stopped, running and waiting for quorum. .TP uidgid.* Information about users/groups which are allowed to make IPC connections to corosync. Entries loaded from configuration file are stored with uidgid.config.* prefix and are pruned on configuration file reload. Dynamic entries has uidgid.* prefix and a configuration file reload doesn't affect them. .TP quorum.cancel_wait_for_all Tells votequorum to cancel waiting for all nodes at cluster startup. Can be used to unblock quorum if notes are known to be down. For pcs use only. .TP config.reload_in_progress This value will be set to 1 (or created) when a corosync.conf reload is started, and set to 0 when the reload is completed. This allows interested subsystems to do atomic reconfiguration rather than changing each key. Note that individual add/change/delete notifications will still be sent during a reload. .TP config.totemconfig_reload_in_progress This key is similar to .B config.totemconfig_reload_in_progress but changed after the totem config trigger is processed. It is useful (mainly) for situations when .B nodelist.local_node_pos must be correctly reinstated before anything else. .SH DYNAMIC CHANGE USER/GROUP PERMISSION TO USE COROSYNC IPC Is the same as in the configuration file. eg: to add UID 500 use .br # corosync-cmapctl -s uidgid.uid.500 u8 1 GID is similar, so to add a GID use .br # corosync-cmapctl -s uidgid.gid.500 u8 1 For removal of permissions, simply delete the key .br # corosync-cmapctl -d uidgid.gid.500 .SH DYNAMIC ADD/REMOVE OF UDPU NODE Eg. To add the node with address 10.34.38.108 and nodeid 3. This node is called NEW and it's not running corosync yet. .PP * Find a node position in the node list which is not used yet. It's recommended that you use highest_number + 1. Let's say output of corosync-cmapctl looks like: .br nodelist.local_node_pos (u32) = 1 .br nodelist.node.0.nodeid (u32) = 1 .br nodelist.node.0.ring0_addr (str) = 10.34.38.106 .br nodelist.node.1.nodeid (u32) = 2 .br nodelist.node.1.ring0_addr (str) = 10.34.38.107 So next node position will be 2. .PP * Add all entries needed for the node on all running nodes, as: .br # corosync-cmapctl -s nodelist.node.2.nodeid u32 3 .br # corosync-cmapctl -s nodelist.node.2.ring0_addr str 10.34.38.108 Always add the ring0_addr key last. The Corosync engine on all nodes should reply with .I notice [TOTEM ] adding new UDPU member {10.34.38.108} message. .PP * Add node information to the configuration file on all nodes so that it will survive a restart of corosync. .PP * Copy and edit configuration file to the NEW node. .PP * Start corosync on the NEW node. Removal of a UDPU node is a very similar, slightly reversed action, so .PP * Stop corosync on the OLD node. .PP * Remove the relevant entries from cmap on all nodes. .PP * Change the configuration file on all nodes. .SH "SEE ALSO" .BR corosync_overview (8), .BR corosync.conf (5), .BR corosync-cmapctl (8) corosync-2.4.3/man/corosync.80000664000076400007640000000567713160753563013045 00000000000000.\"/* .\" * Copyright (C) 2010-2017 Red Hat, Inc. .\" * .\" * All rights reserved. .\" * .\" * Author: Angus Salkeld .\" * .\" * This software licensed under BSD license, the text of which follows: .\" * .\" * Redistribution and use in source and binary forms, with or without .\" * modification, are permitted provided that the following conditions are met: .\" * .\" * - Redistributions of source code must retain the above copyright notice, .\" * this list of conditions and the following disclaimer. .\" * - Redistributions in binary form must reproduce the above copyright notice, .\" * this list of conditions and the following disclaimer in the documentation .\" * and/or other materials provided with the distribution. .\" * - Neither the name of the MontaVista Software, Inc. nor the names of its .\" * contributors may be used to endorse or promote products derived from this .\" * software without specific prior written permission. .\" * .\" * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" .\" * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE .\" * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE .\" * ARE DISCLAIMED.

This service can be optionally loaded into the nodes of a corosync cluster to avoid split-brain situations. It does this by having a number of votes assigned to each system in the cluster and ensuring that only when a majority of the votes are present, cluster operations are allowed to proceed. The service must be loaded into all nodes or none. If it is loaded into a subset of cluster nodes the results will be unpredictable. .PP The following corosync.conf extract will enable votequorum service within corosync: .PP .nf quorum { provider: corosync_votequorum } .fi .PP votequorum reads its configuration from corosync.conf. Some values can be changed at runtime, others are only read at corosync startup. It is very important that those values are consistent across all the nodes participating in the cluster or votequorum behavior will be unpredictable. .PP votequorum requires an expected_votes value to function, this can be provided in two ways. The number of expected votes will be automatically calculated when the nodelist { } section is present in corosync.conf or expected_votes can be specified in the quorum { } section. Lack of both will disable votequorum. If both are present at the same time, the quorum.expected_votes value will override the one calculated from the nodelist. .PP Example (no nodelist) of an 8 node cluster (each node has 1 vote): .nf quorum { provider: corosync_votequorum expected_votes: 8 } .fi .PP Example (with nodelist) of a 3 node cluster (each node has 1 vote): .nf quorum { provider: corosync_votequorum } nodelist { node { ring0_addr: 192.168.1.1 } node { ring0_addr: 192.168.1.2 } node { ring0_addr: 192.168.1.3 } } .fi .SH SPECIAL FEATURES .PP .B two_node: 1 .PP Enables two node cluster operations (default: 0). .PP The "two node cluster" is a use case that requires special consideration. With a standard two node cluster, each node with a single vote, there are 2 votes in the cluster. Using the simple majority calculation (50% of the votes + 1) to calculate quorum, the quorum would be 2. This means that the both nodes would always have to be alive for the cluster to be quorate and operate. .PP Enabling two_node: 1, quorum is set artificially to 1. .PP Example configuration 1: .nf quorum { provider: corosync_votequorum expected_votes: 2 two_node: 1 } .fi .PP Example configuration 2: .nf quorum { provider: corosync_votequorum two_node: 1 } nodelist { node { ring0_addr: 192.168.1.1 } node { ring0_addr: 192.168.1.2 } } .fi .PP NOTES: enabling two_node: 1 automatically enables wait_for_all. It is still possible to override wait_for_all by explicitly setting it to 0. If more than 2 nodes join the cluster, the two_node option is automatically disabled. .PP .B wait_for_all: 1 .PP Enables Wait For All (WFA) feature (default: 0). .PP The general behaviour of votequorum is to switch a cluster from inquorate to quorate as soon as possible. For example, in an 8 node cluster, where every node has 1 vote, expected_votes is set to 8 and quorum is (50% + 1) 5. As soon as 5 (or more) nodes are visible to each other, the partition of 5 (or more) becomes quorate and can start operating. .PP When WFA is enabled, the cluster will be quorate for the first time only after all nodes have been visible at least once at the same time. .PP This feature has the advantage of avoiding some startup race conditions, with the cost that all nodes need to be up at the same time at least once before the cluster can operate. .PP A common startup race condition based on the above example is that as soon as 5 nodes become quorate, with the other 3 still offline, the remaining 3 nodes will be fenced. .PP It is very useful when combined with last_man_standing (see below). .PP Example configuration: .nf quorum { provider: corosync_votequorum expected_votes: 8 wait_for_all: 1 } .fi .PP .B last_man_standing: 1 / .B last_man_standing_window: 10000 .PP Enables Last Man Standing (LMS) feature (default: 0). Tunable last_man_standing_window (default: 10 seconds, expressed in ms). .PP The general behaviour of votequorum is to set expected_votes and quorum at startup (unless modified by the user at runtime, see below) and use those values during the whole lifetime of the cluster. .PP Using for example an 8 node cluster where each node has 1 vote, expected_votes is set to 8 and quorum to 5. This condition allows a total failure of 3 nodes. If a 4th node fails, the cluster becomes inquorate and it will stop providing services. .PP Enabling LMS allows the cluster to dynamically recalculate expected_votes and quorum under specific circumstances. It is essential to enable WFA when using LMS in High Availability clusters. .PP Using the above 8 node cluster example, with LMS enabled the cluster can retain quorum and continue operating by losing, in a cascade fashion, up to 6 nodes with only 2 remaining active. .PP Example chain of events: .nf 1) cluster is fully operational with 8 nodes. (expected_votes: 8 quorum: 5) 2) 3 nodes die, cluster is quorate with 5 nodes. 3) after last_man_standing_window timer expires, expected_votes and quorum are recalculated. (expected_votes: 5 quorum: 3) 4) at this point, 2 more nodes can die and cluster will still be quorate with 3. 5) once again, after last_man_standing_window timer expires expected_votes and quorum are recalculated. (expected_votes: 3 quorum: 2) 6) at this point, 1 more node can die and cluster will still be quorate with 2. 7) one more last_man_standing_window timer (expected_votes: 2 quorum: 2) .fi .PP NOTES: In order for the cluster to downgrade automatically from 2 nodes to a 1 node cluster, the auto_tie_breaker feature must also be enabled (see below). If auto_tie_breaker is not enabled, and one more failure occurs, the remaining node will not be quorate. LMS does not work with asymmetric voting schemes, each node must vote 1. LMS is also incompatible with quorum devices, if last_man_standing is specified in corosync.conf then the quorum device will be disabled. .PP Example configuration 1: .nf quorum { provider: corosync_votequorum expected_votes: 8 last_man_standing: 1 } .fi .PP Example configuration 2 (increase timeout to 20 seconds): .nf quorum { provider: corosync_votequorum expected_votes: 8 last_man_standing: 1 last_man_standing_window: 20000 } .fi .PP .B auto_tie_breaker: 1 .PP Enables Auto Tie Breaker (ATB) feature (default: 0). .PP The general behaviour of votequorum allows a simultaneous node failure up to 50% - 1 node, assuming each node has 1 vote. .PP When ATB is enabled, the cluster can suffer up to 50% of the nodes failing at the same time, in a deterministic fashion. By default the cluster partition, or the set of nodes that are still in contact with the node that has the lowest nodeid will remain quorate. The other nodes will be inquorate. This behaviour can be changed by also specifying .PP .B auto_tie_breaker_node: lowest|highest| .PP \'lowest' is the default, 'highest' is similar in that if the current set of nodes contains the highest nodeid then it will remain quorate. Alternatively it is possible to specify a particular node ID or list of node IDs that will be required to maintain quorum. If a (space-separated) list is given, the nodes are evaluated in order, so if the first node is present then it will be used to determine the quorate partition, if that node is not in either half (ie was not in the cluster before the split) then the second node ID will be checked for and so on. ATB is incompatible with quorum devices - if auto_tie_breaker is specified in corosync.conf then the quorum device will be disabled. .PP Example configuration 1: .nf quorum { provider: corosync_votequorum expected_votes: 8 auto_tie_breaker: 1 auto_tie_breaker_node: lowest } .fi .PP Example configuration 2: .nf quorum { provider: corosync_votequorum expected_votes: 8 auto_tie_breaker: 1 auto_tie_breaker_node: 1 3 5 } .PP .fi .PP .B allow_downscale: 1 .PP Enables allow downscale (AD) feature (default: 0). .PP THIS FEATURE IS INCOMPLETE AND CURRENTLY UNSUPPORTED. .PP The general behaviour of votequorum is to never decrease expected votes or quorum. .PP When AD is enabled, both expected votes and quorum are recalculated when a node leaves the cluster in a clean state (normal corosync shutdown process) down to configured expected_votes. .PP Example use case: .PP .nf 1) N node cluster (where N is any value higher than 3) 2) expected_votes set to 3 in corosync.conf 3) only 3 nodes are running 4) admin requires to increase processing power and adds 10 nodes 5) internal expected_votes is automatically set to 13 6) minimum expected_votes is 3 (from configuration) - up to this point this is standard votequorum behavior - 7) once the work is done, admin wants to remove nodes from the cluster 8) using an ordered shutdown the admin can reduce the cluster size automatically back to 3, but not below 3, where normal quorum operation will work as usual. .fi .PP Example configuration: .nf quorum { provider: corosync_votequorum expected_votes: 3 allow_downscale: 1 } .fi allow_downscale implicitly enabled EVT (see below). .PP .B expected_votes_tracking: 1 .PP Enables Expected Votes Tracking (EVT) feature (default: 0). .PP Expected Votes Tracking stores the highest-seen value of expected votes on disk and uses that as the minimum value for expected votes in the absence of any higher authority (eg a current quorate cluster). This is useful for when a group of nodes becomes detached from the main cluster and after a restart could have enough votes to provide quorum, which can happen after using allow_downscale. .PP Note that even if the in-memory version of expected_votes is reduced, eg by removing nodes or using corosync-quorumtool, the stored value will still be the highest value seen - it never gets reduced. .PP The value is held in the file /var/lib/corosync/ev_tracking which can be deleted if you really do need to reduce the expected votes for any reason, like the node has been moved to a different cluster. .PP .fi .PP .SH VARIOUS NOTES .PP * WFA / LMS / ATB / AD can be used combined together. .PP * In order to change the default votes for a node there are two options: .nf 1) nodelist: nodelist { node { ring0_addr: 192.168.1.1 quorum_votes: 3 } .... } 2) quorum section (deprecated): quorum { provider: corosync_votequorum expected_votes: 2 votes: 2 } .fi In the event that both nodelist and quorum { votes: } are defined, the value from the nodelist will be used. .PP * Only votes, quorum_votes, expected_votes and two_node can be changed at runtime. Everything else requires a cluster restart. .SH BUGS No known bugs at the time of writing. The authors are from outerspace.

It's designed to support multiple clusters and be almost configuration and state free. New clusters are handled dynamically and no configuration file exists. It's also able to run as non-root user - which is recommended. Connection between the .B corosync-qdevice model net client can be optionally configured with TLS client certificate checking. The communication protocol between server and client is designed to be very simple and allow backwards compatibility. .SH OPTIONS .TP .B -4 and its counterpart .B -6 are used to force IPv4 or IPv6 communication. The default is to listen on both address families. .TP .B -d Turn on debug logging. By default the messages sent to syslog are purely operational, this option sends additional debug messages. For even more detail use the .B -d parameter twice. .TP .B -f Do not daemonize, run in the foreground. .TP .B -h Show short help text .TP .B -v Show version and supported communication protocol messages/options. .TP .B -l IP address to listen on. By default the daemon listens on all addresses (wildcard). .TP .B -p TCP port to listen on. Default port is 5403. .TP .B -s Determines if TLS should be used and can be one of .I on/off/required (the default is .I on ). .I on means TLS is enabled but the client is not required to start TLS, .I off means TLS is completely disabled, and .I required means TLS is required. .I on and .I required require the NSS database to be properly initialized by running the .B corosync-qnetd-certutil command. .TP .B -c can be set to .I on/off. This option only makes sense if TLS is enabled. When .B -c is .I on a client is required to send its client certificate (default). .TP .B -m Maximum simultaneous clients. The default is 0 which means no limit. .TP .B -S Set advanced settings described in its own section below. This option shouldn't be generally used because most of the options are not safe to change. .SH UNPRIVILEGED USER CONFIGURATION It's generally recommended to run .B corosync-qnetd as a non root user. If you get a package from a distribution its highly possible that the packager has done all the hard work for you. If the installation is performed from source code, a few steps have to be taken. First it's necessary to create an unprivileged user/group. The following commands can be used (executed as root): .nf # groupadd -r coroqnetd # useradd -r -g coroqnetd -d / -s /sbin/nologin -c "User for corosync-qnetd" coroqnetd .fi The next step is to set the correct owner and group on /etc/corosync/qnetd and /var/run/corosync-qnetd directories. .nf # chown -R coroqnetd:coroqnetd /etc/corosync/qnetd /var/run/corosync-qnetd .fi Some systems have the /var/run directory on a tmpfs file system which gets discarded after a reboot. The solution is to use an initscript which takes care of the /var/run/corosync-qnetd creation and sets the correct owner and permissions. For systems with systemd it's possible to use a tmpfile.d configuration file (installed by default if systemd is enabled during corosync compilation). The last step is to make sure .B corosync-qnetd is really executed as an unprivileged user. For initscript systems it's enough to set the line COROSYNC_QNETD_RUNAS in /etc/(sysconfig|default)/corosync-qnetd file. If the file is not already installed then use the one provided in the corosync source code (init/corosync-qnetd.sysconfig.example). For systemd, overwrite/copy the corosync-qnetd.service unit file and uncomment/change the "User=" directive. .SH TLS CONFIGURATION For TLS to work its necessary to create the NSS database. If pcs is used then the following steps are not needed because pcs does them automatically. .B corosync-qnetd-certutil is the tool to perform required actions. Just run: .nf # corosync-qnetd-certutil -i .fi If TLS is not required then simply edit /etc/(sysconfig|default)/corosync-qnetd or systemd unit file and add the parameter .B -s .I off in the proper place. .SH ADVANCED SETTINGS Set by the .B -S option. The default value is shown in parantheses. .TP .B listen_backlog Parameter passed to the listen syscall on the network socket. (10) .TP .B max_client_send_buffers Maximum number of send buffers for one client. (32) .TP .B max_client_send_size Maximum size of one send buffer (message) to be sent to a client. (32768) .TP .B max_client_receive_size Maximum size of the receive buffer for a client message (maximum allowed message size received by client). (32768) .TP .B nss_db_dir NSS database directory.

Faults occur for various reasons: .PP * Application Faults .PP * Middleware Faults .PP * Operating System Faults .PP * Hardware Faults The major focus of high availability in the past has been to mask hardware faults. Faults in other components of the system have gone unsolved until Corosync. Corosync is designed for applications to replicate their state to up to 16 processors. The processors all contain a replica of the application state. The corosync project provides a group message API called CPG. The project developers recommend CPG be used for most applications. The CPG service implements a closed group messaging model presenting extended virtual synchrony guarantees. To manage conditions where the process executing the CPG application exchange fails, we provide the Simple Availability Manager (sam) to provide simple application restart. .SH QUICKSTART The corosync executive must be configured. In the directory conf in the source distribution are several files that must be copied to the /etc/corosync directory. If corosync is packaged by a distro, this may be complete. The directory contains the file corosync.conf. Please read the corosync.conf(5) man page for details on the configuration options. The corosync project will work out of the box with the default configuration options, although the administrator may desire different options. The corosync executive uses cryptographic techniques to ensure authenticity and privacy of the messages. In order for corosync to be secure and operate, a private key must be generated and shared to all processors. First generate the key on one of the nodes: unix# corosync-keygen .br Corosync Cluster Engine Authentication key generator. .br Gathering 1024 bits for key from /dev/random. .br Press keys on your keyboard to generate entropy. .br Writing corosync key to /etc/corosync/authkey. .PP After this operation, a private key will be in the file /etc/corosync/authkey. This private key must be copied to every processor in the cluster. If the private key isn't the same for every node, those nodes with nonmatching private keys will not be able to join the same configuration. Copy the key to some security transportable storage or use ssh to transmit the key from node to node. Then install the key with the command: unix#: install -D --group=0 --owner=0 --mode=0400 /path_to_authkey/authkey /etc/corosync/authkey If a message "Invalid digest" appears from the corosync executive, the keys are not consistent between processors. Finally run the corosync executive. If corosync is packaged from a distro, it may be set to start on system start. It may also be turned off by default in which case the init script for corosync must be enabled. .SH USING LIBRARIES The corosync libraries have header files which must be included in the developer's application. Once the header file is included, the developer can reference the corosync interfaces. The corosync project recommends to distros to place include files in /usr/include/corosync. .SH IPv6 The corosync project supports both IPv4 and IPv6 network addresses. The entire cluster must use either IPv4 or IPv6 for the cluster communication mechanism. In order to use IPv6, IPv6 addresses must be specified in the bindnetaddr and mcastaddr fields in the configuration file. The nodeid field must also be set. An example of this is: nodeid: 2 bindnetaddr: fec0::1:a800:4ff:fe00:20 mcastaddr: ff05::1 To configure a host for IPv6, use the ifconfig program to add interfaces: box20: ifconfig eth0 add fec0::1:a800:4ff:fe00:20/64 box30: ifconfig eth0 add fec0::1:a800:4ff:fe00:30/64 If the /64 is not specified, a route for the IPv6 network will not be configured which will cause significant problems. Make sure a route is available for IPv6 traffic. .SH ARCHITECTURE The corosync libraries are a thin IPC interface to the corosync executive. The corosync executive implements the functionality of the corosync APIs for distributed coming. The corosync executive uses the Totem extended virtual synchrony protocol. The advantage to the end user is excellent performance characteristics and a proven protocol with excellent reliability. This protocol connects the processors in a configuration together so they may communicate. .SH ENVIRONMENT VARIABLES The corosync executive process uses four environment variables during startup. If these environment variables are not set, defaults will be used. .TP COROSYNC_MAIN_CONFIG_FILE This specifies the fully qualified path to the corosync configuration file. The default is /etc/corosync/corosync.conf. .TP COROSYNC_TOTEM_AUTHKEY_FILE This specifies the fully qualified path to the shared key used to authenticate and encrypt data used within the Totem protocol. The default is /etc/corosync/authkey. .SH SECURITY The corosync executive optionally encrypts all messages sent over the network using the AES-128 cipher. The corosync executive uses HMAC and SHA1 to authenticate all messages. The corosync executive library uses NSS as a pseudo random number generator. If membership messages can be captured by intruders, it is possible to execute a denial of service attack on the cluster. In this scenario, the cluster is likely already compromised and a DOS attack is the least of the administration's worries. The security in corosync does not offer perfect forward secrecy because the keys are reused. It may be possible for an intruder by capturing packets in an automated fashion to determine the shared key. No such automated attack has been published as of yet. In this scenario, the cluster is likely already compromised to allow the long-term capture of transmitted data. For security reasons, the corosync executive binary should NEVER be setuid or setgid in the filesystem. .SH BUGS None that are known. .SH "SEE ALSO" .BR corosync.conf (5), .BR corosync-keygen (8), .BR cpg_overview (8), .BR sam_overview (8) .PP corosync-2.4.3/man/cpg_model_initialize.3.in0000664000076400007640000001470413160753563015747 00000000000000.\"/* .\" * Copyright (c) 2010 Red Hat, Inc. .\" * .\" * All rights reserved. .\" * .\" * Author: Jan Friesse .\" * Author: Christine Caulfield .\" * .\" * This software licensed under BSD license, the text of which follows: .\" * .\" * Redistribution and use in source and binary forms, with or without .\" * modification, are permitted provided that the following conditions are met: .\" * .\" * - Redistributions of source code must retain the above copyright notice, .\" * this list of conditions and the following disclaimer. .\" * - Redistributions in binary form must reproduce the above copyright notice, .\" * this list of conditions and the following disclaimer in the documentation .\" * and/or other materials provided with the distribution. .\" * - Neither the name of the MontaVista Software, Inc. nor the names of its .\" * contributors may be used to endorse or promote products derived from this .\" * software without specific prior written permission. .\" * .\" * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" .\" * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE .\" * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE .\" * ARE DISCLAIMED.

The .I handle argument is connection to CMAP database obtained by calling .B cmap_initialize(3) function. .I key_name is name of key to get value from. .I value is pointer to preallocated data used as storage for data, but can be also NULL, and then only .I value_len and/or .I type is returned (both of them can also be NULL, allowing function to be used only for test of existence of key). If .I value is not NULL, actual length of value in map is checked against .I *value_len. If .I *value_len is shorter then length of value in map, error CS_ERR_INVALID_PARAM is returned. After successful copy of value, .I *value_len is set to actual length of value in map. Parameter .I type is pointer to memory, where type of value is stored after successful return.

Each application uses the .I handle argument to uniquely identify the connection. .PP The .I dispatch_types argument is used to identify the type of dispatch to execute. The possible types are CS_DISPATCH_ONE, CS_DISPATCH_ALL and CS_DISPATCH_BLOCKING. The dispatch values have the following meanings: .TP .B CS_DISPATCH_ONE Dispatch at least one callback, blocking until the callback is dispatched. .TP .B CS_DISPATCH_ALL Dispatch all waiting callbacks without blocking to wait for any callbacks. .TP .B CS_DISPATCH_BLOCKING Dispatch all callbacks blocking indefinitely. This is used in a threaded program where a thread is created, and then cs_dispatch() is called immediately from the created thread to execute callbacks. .TP .B CS_DISPATCH_ONE_NONBLOCKING Dispatch at most one callback. If there is no pending callback, CS_ERR_TRY_AGAIN is returned. .PP It's needed to call .B cmap_track_add(3) to add tracked items and receive callbacks. .SH RETURN VALUE .P This call returns the CS_OK value if successful, otherwise an error is returned. .SH "SEE ALSO" .BR cmap_track_add (3), .BR cmap_track_delete (3), .BR cmap_overview (8) corosync-2.4.3/man/corosync-qdevice-tool.80000664000076400007640000001064213172367263015423 00000000000000.\"/* .\" * Copyright (C) 2016-2017 Red Hat, Inc. .\" * .\" * All rights reserved. .\" * .\" * Author: Jan Friesse .\" * .\" * This software licensed under BSD license, the text of which follows: .\" * .\" * Redistribution and use in source and binary forms, with or without .\" * modification, are permitted provided that the following conditions are met: .\" * .\" * - Redistributions of source code must retain the above copyright notice, .\" * this list of conditions and the following disclaimer. .\" * - Redistributions in binary form must reproduce the above copyright notice, .\" * this list of conditions and the following disclaimer in the documentation .\" * and/or other materials provided with the distribution. .\" * - Neither the name of Red Hat, Inc. nor the names of its .\" * contributors may be used to endorse or promote products derived from this .\" * software without specific prior written permission. .\" * .\" * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" .\" * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE .\" * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE .\" * ARE DISCLAIMED.

If the active process fails to respond to the healthcheck request sent by the SAM server, it will be sent a user configurable signal (default SIGTERM) to request shutdown of the application. After a configured time interval, the process will be forcibly killed by being sent a SIGKILL signal. Once the active process terminates, the SAM server will create a new active process. .P The Simple Availability Manager is meant to be used in conjunction with the cpg service. Used together, it is possible to restart a cpg process that fails healthchecking during operation. .P The main features of SAM include: .RS .IP \(bu 3 A configurable recovery policy. .IP \(bu 3 A configurable time interval for health check operations. .IP \(bu 3 A notification via signal before recovery action is taken. .IP \(bu 3 A mechanism to indicate to the application the number of times an active process has been created by the SAM server. .IP \(bu 3 Both application driven health checking and event driven health checking. .RE .SH Initializing SAM .P The SAM library is initialized by \fBsam_initialize(3)\fR. \fBsam_initalize(3)\fR may only be called once per process. Calling it more then once has undefined results and is not recommended or tested. .SH Setting warning callback .P User configurable signal (default \fISIGTERM\fR) is sent to the application when a recovery action is planned. The application can use the \fBsignal(3)\fR system call to monitor for this signal. .P There are no special constraints on what SAM apis may be called in a warning callback. After \fItime_interval\fR expires, a SIGKILL signal is sent to the active process to force its termination. .SH Registering the active process .P The active process is registered with SAM by calling \fBsam_register(3)\fR. This function should only be called one time in a process. After a recovery action is taken, the new active process will begin execution at the next line of code in a user process after \fBsam_register(3)\fR. .SH Enabling event driven healthchecking .P Two types of healthchecking are available to the user. The first model is one where the user application healthchecks during its normal operation. It is never requested to healtcheck, and if the active process doesn't respond within the time interval, the process will be restarted. .P A more useful mechanism for healthchecking is event driven healthchecking. Because this model is directed by the SAM server, It isn't necessary to guess or add timers to the active process to signal a healthcheck operation is successful. To use event driven healthchecking, the \fBsam_hc_callback_register(3)\fR function should be executed. .SH Quorum integration .P SAM has special policies (\fISAM_RECOVERY_POLICY_QUIT\fR and \fISAM_RECOVERY_POLICY_RESTART\fR) for integration with quorum service. This policies changes SAM behaviour in two aspects. .RS .IP \(bu 3 Call of \fBsam_start(3)\fR blocks until corosync becomes quorate .IP \(bu 3 User selected recovery action is taken immediately after lost of quorum. .RE .SH Storing user data .P Sometimes there is need to store some data, which survives between instances. One can in such case use files, databases, ... or much simpler in memory solution presented by \fBsam_data_store(3)\fR, \fBsam_data_restore(3)\fR and \fBsam_data_getsize(3)\fR functions. .SH Confdb integration .P SAM has policy flag used for confdb system integration (\fISAM_RECOVERY_POLICY_CONFDB\fR). If process is registered with this flag, new confdb object PROCESS_NAME:PID is created with following keys: .RS .IP \(bu 3 \fIrecovery\fR - will be quit or restart depending on policy .IP \(bu 3 \fIpoll_period\fR - period of health checking in milliseconds .IP \(bu 3 \fIlast_updated\fR - Timestamp (in nanoseconds) of the last health check. .IP \(bu 3 \fIstate\fR - state of process (can be one of registered, started, failed, waiting for quorum) .RE .P Object is automatically deleted if process exits with stopped health checking. .P Confdb integration with corosync watchdog can be used in implicit and explicit way. .P Implicit way is achieved by setting recovery policy to QUIT and let process exit with started health checking. If this happened, object is not deleted and corosync watchdog will take required action. .P Explicit way is useful for situations, when developer can deal with some non-fatal fall of application. This mode is achieved by setting policy to RESTART and using SAM same as without Confdb integration. If real fail is needed (like too many restarts at all, per/sec, ...), it's possible to use \fBsam_mark_failed(3)\fR and let corosync watchdog take required action. .SH BUGS .SH "SEE ALSO" .BR sam_initialize (3), .BR sam_data_getsize (3), .BR sam_data_restore (3), .BR sam_data_store (3), .BR sam_finalize (3), .BR sam_mark_failed (3), .BR sam_start (3), .BR sam_stop (3), .BR sam_register (3), .BR sam_warn_signal_set (3), .BR sam_hc_send (3), .BR sam_hc_callback_register (3) corosync-2.4.3/man/quorum_trackstart.3.in0000664000076400007640000000577013172367236015373 00000000000000.\"/* .\" * Copyright (c) 2012 Red Hat, Inc. .\" * .\" * All rights reserved. .\" * .\" * Author: Fabio M.

The default directory for the database is /etc/corosync/qnetd. This directory must be writeable by the current user.

Each application uses the .I handle argument to uniquely identify the connection. .PP The .I dispatch_types argument is used to identify the type of dispatch to execute. The possible types are defined by the structure: .IP .RS .ne 18 .nf .ta 4n 30n 33n typedef enum { CS_DISPATCH_ONE, CS_DISPATCH_ALL, CS_DISPATCH_BLOCKING } cpg_dispatch_t; .ta .fi .RE .IP .PP .PP The dispatch values have the following meanings: .TP .B CS_DISPATCH_ONE Dispatch atleast one callback, blocking until the callback is dispatched. .TP .B CS_DISPATCH_ALL Dispatch all waiting callbacks without blocking to wait for any callbacks. .TP .B CS_DISPATCH_BLOCKING Dispatch all callbacks, blocking indefinitely. This is used in a threaded program where a thread is created, and then cpg_dispatch() is called immediately from the created thread to execute callbacks. .TP .B CS_DISPATCH_ONE_NONBLOCKING Dispatch at most one callback. If there is no pending callback, CS_ERR_TRY_AGAIN is returned. .SH RETURN VALUE This call returns the CS_OK value if successful, otherwise an error is returned. .PP .SH ERRORS The errors are undocumented. .SH "SEE ALSO" .BR cpg_overview (8), .BR cpg_initialize (3), .BR cpg_finalize (3), .BR cpg_fd_get (3), .BR cpg_dispatch (3), .BR cpg_join (3), .BR cpg_leave (3), .BR cpg_mcast_joined (3), .BR cpg_membership_get (3) .BR cpg_zcb_alloc (3) .BR cpg_zcb_free (3) .BR cpg_zcb_mcast_joined (3) .BR cpg_context_get (3) .BR cpg_context_set (3) .BR cpg_local_get (3) .PP corosync-2.4.3/man/quorum_getquorate.3.in0000664000076400007640000000514713160753563015366 00000000000000.\"/* .\" * Copyright (c) 2012 Red Hat, Inc. .\" * .\" * All rights reserved. .\" * .\" * Author: Fabio M.

Authentication 2. Secrecy Library Interface ----------------- The corosync executive authenticates every library user. The library is only allowed to access services if it's GID is corosync or 0. Unauthorized library users are rejected. The corosync group is a trusted group. If the administrator doesn't trust the application, it should not be added to the group! Any member of the corosync group could potentially send a malformed request to the executive and cause it to fault. Group Messaging Interface ------------------------- Group messaging uses UDP/IP to communicate with other corosync executives using messages. It is possible without authentication of every packet that an attacker could forge messages. These forged messages could fault the corosync executive distributed state machines. It would also be possible to corrupt end applications by forging changes. Since messages are sent using UDP/IP it would be possible to snoop those messages and rebuild sensitive data. To solve these problems, the group messaging interface uses two new interfaces interal to it's implementation: 1. encrypt_and_sign - encrypts and signs a message securely 2. authenticate_and_decrypt - authenticates and decrypts a message securely When the executive wants to send a message over the network, it uses encrypt_and_sign to prepare the message to be sent. When the executive wants to receive a message from the network, it uses authenticate_and_decrypt to verify the message is valid and decrypt it. Corosync uses AES256/SHA-1 which from the Mozilla Network Security Services (libnss) library. The internal functions utilize the following algorithms: sha1 - hash algorithm secure for using with hmac hmac - produces a 16 byte digest from any length input Every message starts with a struct security { unsigned char digest[20]; A one way hash digest unsigned char salt[16]; A securely generated random number } USING LIBNSS ------------ When corosync is started up libnss is initialised, the private key is read into memory and stored for later use by the code. When a message is sent (encrypt_and_sign): ------------------------------------------ - The message is encrypted using AES. - A digest of that message is then created using SHA256 and based on the private key. - the message is then transmitted. When a message is received (decrypt_and_authenticate): - A Digest of the encrypted message is created using the private key - That digest is compared to the one in the message security_header - If they do not match the packet is rejected - If they do match then the message is decrypted using the private key. - The message is processed.
