It is developped in C and available under the BSD license. It splits a list of directories and file trees into a certain number of partitions, trying to produce partitions with the same size and number of files. It can also produce partitions with a given number of files or a limited size. Once generated, partitions are either printed as file lists to stdout (default) or to files. Those lists can then be used by third party programs. Fpart also includes a live mode, which allows it to crawl very large filesystems and produce partitions in live. Hooks are available to act on those partitions (e.g. immediatly start a transfer using rsync(1)) without having to wait for the filesystem traversal job to be finished. Used this way, fpart can be seen as a powerful data migration tool. Compatibility : *************** Fpart has been successfully tested on : * FreeBSD 7.x, 8.x, 9.x (i386, amd64) * GNU/Linux (x86_64, arm) * Solaris 9, 10 (Sparc, i386) * NetBSD (amd64, alpha) and will probably work on other operating systems too (*). (*) fpart built as a static binary within a Debian (armel) chroot will give you a powerful tool for backing-up your Android (arm) phone ;-) Examples - common usage : ************************* The following will produce 3 partitions, with (approximatively) the same size and number of files. Three files : "var-parts.[0-2]", are generated as output : $ fpart -n 3 -o var-parts /var $ ls var-parts* var-parts.0 var-parts.1 var-parts.2 $ head -n 2 var-parts.0 /var/some/file1 /var/some/file2 The following will produce partitions of 4.3 GB, containing music files ready to be burnt to a DVD (for example). Files "music-parts.[0-n]", are generated as output : $ fpart -s 4617089843 -o music-parts /path/to/my/music The following will produce partitions containing 10000 files each by examining /usr first and then /home and display only partition 0 on stdout : $ find /usr ! -type d | fpart -f 10000 -i - /home | grep '^0:' The following will produce two partitions by re-using du(1) output. Fpart will not examine the filesystem but instead re-use arbitrary values printed by du(1) and sort them : $ du * | fpart -n 2 -a Examples - live mode : ********************** By default, fpart will wait for FS crawling to terminate before generating and displaying partitions. If you use the live mode (option -L), fpart will display each partition as soon as it is complete. You can combine this option with hooks; they will be triggered just before (pre-part hook, option -w) or after (post-part hook, option -W) partitions' completion. Hooks provide several environment variables (see fpart(1)); they are a convenient way of getting information about fpart's and partition's current states. For example, ${FPART_PARTFILENAME} will contain the name of the output file of the partition that has just been generated; using that variable within a post-part hook permits starting manipulating the files just after partition generation. See the following example : $ mkdir foo && touch foo/{bar,baz} $ fpart -L -f 1 -o /tmp/part.out -W \ 'echo == ${FPART_PARTFILENAME} == ; cat ${FPART_PARTFILENAME}' foo/ == /tmp/part.out.0 == foo/bar == /tmp/part.out.1 == foo/baz 2 file(s) found. This example crawls foo/ in live mode (option -L). For each file (option -f, 1 file per partition), it generates a partition into /tmp/part.out. (option -o; is the partition index and will be automatically added by fpart) and executes the following post-part hook (option -W) : echo == ${FPART_PARTFILENAME} == ; cat ${FPART_PARTFILENAME} This hook will display the name of current partition's output file name as well as display its contents. Examples - migrating data : *************************** Here is a more complex example that will show you how to use fpart, GNU Parallel and Rsync to split up a directory and immediately schedule data synchronization of smaller lists of files, while FS crawling goes on. We will be synchronizing data from /data/src to /data/dest. First, go to the source directory (as rsync's --files-from option takes a file list relative to its source directory) : $ cd /data/src Then, run fpart from here : $ fpart -L -f 10000 -x '.snapshot' -x '.zfs' -Z -o /tmp/part.out -W \ '/usr/local/bin/sem -j 3 "/usr/local/bin/rsync -av --files-from=${FPART_PARTFILENAME} /data/src/ /data/dest/"' . This command will start fpart in live mode (option -L), making it generate partitions during FS crawling. Fpart will produce partitions containing at most 10000 files each (option -f), will skip files and folders named '.snapshot' or '.zfs' (option -x) and will list empty and non-accessible directories (option -Z; that option is necessary when working with rsync to make sure the whole file tree will be re-created within the destination directory). Last but not least, each partition will be written to /tmp/part.out. (option -o) and used within the post-part hook (option -W), run immediately by fpart once the partition is complete : /usr/local/bin/sem -j 3 "/usr/local/bin/rsync -av --files-from=${FPART_PARTFILENAME} /data/src/ /data/dest/" This hook is itself a nested command. It will run GNU Parallel's sem scheduler (any other scheduler will do) to run at most 3 rsync in parallel. The scheduler will finally trigger the following command : /usr/local/bin/rsync -av --files-from=${FPART_PARTFILENAME} /data/src/ /data/dest/ where ${FPART_PARTFILENAME} will be part of rsync's environment when it runs and contain the file name of the partition that has just been generated. That's all, folks ! Pretty simple, isn't it ? In this example, FS crawling and data transfer are run from the same -local- machine, but you can use it as the basis of a much sophisticated solution : at work, by using a cluster of machines connected to our filers through NFS and running Open Grid Scheduler, we successully migrated over 400 TB of data. Note : several fpart runs can be launched using the above example ; you will perform incremental synchronisations. That is, deleted files from the source directory will not be removed from destination unless rsync's --delete option is used. Unfortunately, this option cannot be used with a list of files (files that do not appear in the list are just ignored). To use the --delete option in conjunction with fpart, you *have* to provide rsync's --files-from option a list of directories (only). Fpart's -d option can do the trick but it will probaby not generate partitions having the same size (if you choose to use that method anyway, do not forget to use rsync's -r option too). Another - simpler - method if you plan to perform several synchronisations is to use a single, last rsync to delete extra files from destination using the --delete option. This simple rsync pass will not transfer data but only delete files from destination directory. Limitations : ************* Fpart will *NOT* modify data, it will *NOT* split your files ! As a consequence, if you have a directory containing several small files and a huge one, it will be unable to produce partitions with the same size. Fpart does magic, but not that much ;-) If you provide several paths to fpart, it will examine all of them. If those paths overlap or if the same path is specified more than once, same files will appear more than once within generated partitions. This is not a bug, fpart does not deduplicate FS crawling results. Installing : ************ For FreeBSD users, fpart is already available in ports, see sysutils/fpart. You can install fpart from there or from sources if you really need the latest revision. Installing from sources is simple. First, if there is no 'configure' script in the main directory, run : $ autoreconf -i (autoreconf comes from the GNU autotools), then run : $ ./configure $ make to configure and build fpart. Finally, install fpart (as root) : # make install See also : ********** See fpart(1) for more details. The partition problem is detailed here : http://en.wikipedia.org/wiki/Partition_problem and here : http://en.wikipedia.org/wiki/Bin_packing_problem I am sure you will also be interested in : https://github.com/jbd/packo which was developped by Jean-Baptiste Denis as the original proof of concept.

This option cannot be used in conjunction with .Fl f , .Fl s or .Fl L . .It Ic -f Ar files Create partitions containing at most .Ar files files. This option can be used in conjunction with .Fl s and .Fl L . .It Ic -s Ar size Create partitions with a maximum size of .Ar size bytes. With this option, partition 0 may be used to handle files that do not fit in a regular partition, given the provided .Ar size limit. This option can be used in conjunction with .Fl f and .Fl L . .El .Sh INPUT CONTROL .Bl -tag -width indent .It Ic -i Ar infile Read file list from .Ar infile . If .Ar infile is .Dq Li "-" , then list is read from stdin. .It Fl a Input contains arbitrary values; just sort them (do not crawl filesystem). Input must follow the .Dq Li "size(blank)path" scheme. This option is incompatible with crawling-related options. .El .Sh OUTPUT CONTROL .Bl -tag -width indent .It Ic -o Ar outfile Output partitions' contents to .Ar outfile template. Multiple files will be generated given that template. Each .Ar outfile will get partition number as a suffix. If .Ar outfile is .Dq Li "-" , then partitions will be printed to stdout, with partition number used as a prefix (so you can grep partitions you are interested in, or do whatever you want). .It Fl e When adding directories (see .Sx DIRECTORY HANDLING ), add an ending .Dq Li "/" to each directory entry. .It Fl v Verbose mode (may be specified more than once). .El .Sh FILESYSTEM CRAWLING CONTROL .Bl -tag -width indent .It Fl l Follow symbolic links (default: do not follow). .It Fl b Do not cross filesystem boundaries (default: cross). .It Ic -y Ar pattern Include files or directories matching .Ar pattern only (and discard all other files). This option may be specified several times. It does not apply when computing size of directories to be added as leaf entries (the computed size will then include every file within directory). .It Ic -Y Ar pattern Same as .Fl y but case insensitive. This option may not be available on your platform (at least FreeBSD and GNU/Linux support it, Solaris does not). .It Ic -x Ar pattern Exclude files or directories matching .Ar pattern . This option can be used in conjunction with .Fl y and .Fl Y . In this case, exclusion is performed after. This option may be specified several times. It does not apply when computing size of directories to be added as leaf entries (the computed size will then include every file within directory). .It Ic -X Ar pattern Same as .Fl x but case insensitive. This option may not be available on your platform (at least FreeBSD and GNU/Linux support it, Solaris does not). .El .Sh DIRECTORY HANDLING .Bl -tag -width indent .It Fl z Pack empty directories. By default, fpart will pack files only (except when using the .Fl d or .Fl D options). This option can be useful for tools such as .Xr rsync 1 to be able to recreate a full file tree when used with fpart (e.g. using rsync's --files-from option). See the .Fl Z option to also pack un-readable directories. .It Fl Z Implies .Fl z . Treat un-readable directories as empty, causing them to be packed anyway. .It Ic -d Ar depth After a certain .Ar depth , pack directories instead of files (directories themselves will be added to partitions, instead of their content). .It Fl D Implies .Fl z . Pack leaf directories: if a directory contains files only, it will be packed as a single entry. .El .Sh LIVE MODE .Bl -tag -width indent .It Fl L Live mode (default: disabled). When using this mode, partitions will be generated while crawling filesystem. This option saves time and memory, but does not give partition 0 a special meaning (see option .Fl s ). As a consequence, it can generate partitions larger than the size specified with option .Fl s . This option can be used in conjunction with options .Fl f and .Fl s , but not with option .Fl n . .It Ic -w Ar cmd When using live mode, execute .Ar cmd when starting a new partition (before having opened next output file, if any). .Ar cmd is run in a specific environment that provides several variables describing the state of the program: .Ev FPART_HOOKTYPE ("pre-part" or "post-part"), .Ev FPART_PARTFILENAME (current partition's output file name), .Ev FPART_PARTNUMBER (current partition number), .Ev FPART_PARTSIZE (current partition size), .Ev FPART_PARTNUMFILES (number of files in current partition), .Ev FPART_PID (PID of fpart). Note that variables may or may not be defined, depending of requested options and current partition's state when the hook is triggered. Also, note that hooks are executed in a synchronous way while crawling filesystem, so 1) avoid executing commands that take a long time to return as it slows down filesystem crawling and 2) do not presume cwd (PWD) is the one fpart has been started in, as it is regularly changed to speed up crawling (use abolute paths within hooks). .It Ic -W Ar cmd Same as .Fl w , but executes .Ar cmd when finishing a partition (after having closed last output file, if any). .El .Sh SIZE HANDLING .Bl -tag -width indent .It Ic -p Ar num Preload each partition with .Ar num bytes. .It Ic -q Ar num Overload each file size with .Ar num bytes. .It Ic -r Ar num Round each file size up to next .Ar num bytes multiple. This option can be used in conjunction with overloading, which is done *before* rounding. .El .Sh EXAMPLES Here are some examples: .Bl -tag -width indent .It Li "fpart -n 3 -o var-parts /var" Produce 3 partitions, with (hopefully) the same size and number of files. Three files: var-parts.0, var-parts.1 and var-parts.2 are generated as output. .It Li "fpart -s 4724464025 -o music-parts /path/to/music ./*.mp3" Produce partitions of 4.4 GB, containing music files from /path/to/music as well as MP3 files from current directory; with such a partition size, each partition content will be ready to be burnt to a DVD. Files music-parts.0 to music-parts.n, are generated as output. .It Li "find /usr ! -type d | fpart -f 10000 -i - /home | grep '^0:'" Produce partitions containing 10000 files each by examining /usr first and then /home and display only partition 0 on stdout. .It Li "du * | fpart -n 2 -a" Produce two partitions by using .Xr du 1 output. Fpart will not examine the file system but instead use arbitrary values printed by .Xr du 1 and sort them. .El .Sh SEE ALSO .Xr rsync 1 , .Xr find 1 , .Xr du 1 , .Xr grep 1 .Sh AUTHOR, AVAILABILITY Fpart has been written by .An Gana\(:el LAPLANCHE and is available under the BSD license on .Lk http://contribs.martymac.org .Sh BUGS No bug known (yet). fpart-0.9/man/Makefile.am000644 001751 001751 00000000030 12162232242 016770 0ustar00martymacmartymac000000 000000 dist_man_MANS = fpart.1
