.SH DESCRIPTION
.B lfs
free up disk space. An <endrec> of 0 indicates the current last record.
Changelog consumers must be registered on the MDT node using \fBlctl\fR.
.TP
-.B check
-Display the status of MDS or OSTs (as specified in the command) or all the servers (MDS and OSTs)
-.TP
-.B df
-See
-.BR lfs-df (1)
-for details of
-.B lfs df
-usage.
-.TP
-.B find
-To search the directory tree rooted at the given dir/file name for the files that match the given parameters: \fB--atime\fR (file was last accessed N*24 hours ago), \fB--ctime\fR (file's status was last changed N*24 hours ago), \fB--mtime\fR (file's data was last modified N*24 hours ago), \fB--obd\fR (file has an object on a specific OST or OSTs), \fB--size\fR (file has size in bytes, or \fBk\fRilo-, \fBM\fRega-, \fBG\fRiga-, \fBT\fRera-, \fBP\fReta-, or \fBE\fRxabytes if a suffix is given), \fB--type\fR (file has the type: \fBb\fRlock, \fBc\fRharacter, \fBd\fRirectory, \fBp\fRipe, \fBf\fRile, sym\fBl\fRink, \fBs\fRocket, or \fBD\fRoor (Solaris)), \fB--uid\fR (file has specific numeric user ID), \fB--user\fR (file owned by specific user, numeric user ID allowed), \fB--gid\fR (file has specific group ID), \fB--group\fR (file belongs to specific group, numeric group ID allowed), \fB--layout\fR (file has a raid0 layout or is released). The option \fB--maxdepth\fR limits find to decend at most N levels of directory tree. The options \fB--print\fR and \fB--print0\fR print full file name, followed by a newline or NUL character correspondingly. Using \fB!\fR before an option negates its meaning (\fIfiles NOT matching the parameter\fR). Using \fB+\fR before a numeric value means \fIfiles with the parameter OR MORE\fR, while \fB-\fR before a numeric value means \fIfiles with the parameter OR LESS\fR.
+.B check <mgts|mdts|osts|all>
+Display the status of the MGTs, MDTs or OSTs (as specified in the command) or
+all the servers (MGTs, MDTs and OSTs).
+.TP
+.B data_version [-nrw] <filename>
+Display the current version of file data. If -n is specified, the data version
+is read without taking a lock. As a consequence, the data version could be
+outdated if there are dirty caches on filesystem clients, but this option will
+not force data flushes and has less of an impact on the filesystem. If -r is
+specified, the data version is read after dirty pages on clients are flushed. If
+-w is specified, the data version is read after all caching pages on clients are
+flushed.
+
+Even with -r or -w, race conditions are possible and the data version should be
+checked before and after an operation to be confident the data did not change
+during it.
+
+The data version is the sum of the last committed transaction numbers of all
+data objects of a file. It is used by HSM policy engines for verifying that file
+data has not been changed during an archive operation or before a release
+operation, and by OST migration, primarily for verifying that file data has not
+been changed during a data copy, when done in non-blocking mode.
.TP
.B getname [-h]|[path ...]
Report all the Lustre mount points and the corresponding Lustre filesystem
that is located on a lustre mounted file system then only the OSTs belonging
to that filesystem are displayed.

-.br
-List the striping information for a given filename or directory tree.
-By default the stripe count, size, and offset will be returned. If you
-only want specific striping information then the options of
-.BR --count ,
-.BR --size ,
-.BR --index ,
-.BR --offset ,
-.BR --layout ,
-.BR --fid ,
-.BR --generation ,
-or
-.B --pool
-can be used to return only the specific fields.
-.br
-If the
-.B --raw
-option is specified, the stripe information is printed without substituting the
-filesystem's default values for unspecified fields. If the striping EA is not
-set, 0, 0, and -1 will be printed for the stripe count, size, and offset
-respectively.
-In the case where you only want details about the files' object id
-information then the
-.B --quiet
-option is used. Additional information available about striping can be
-displayed with
-.BR --verbose .
-The default behavior when a directory is specified is to list the striping
-information for all files within the specified directory (like
-.RB ' "ls -l" ') .
-This can be expanded with
-.B --recursive
-which will recurse into all subdirectories.
-If you wish to get striping information for only the specified directory, then
-.B --directory
-can be used to limit the information, like
-.RB ' "ls -d" ').
-You can limit the returned files to those with objects on a specific OST with
-.BR --obd .
-To show only the FID use
-.BR --fid .
-The layout generation can be printed with the
-.B --generation
-option.

-.B setstripe [--stripe-count|-c stripe_count] [--stripe-size|-S stripe_size]
- \fB[--stripe-index|-i start_ost_index] [--pool <poolname>]
- \fB[--ost-index|-o <ost_indices>] <dirname|filename>\fR
-.br
-To create a new file, or set the directory default, with the specified striping
-parameters. The
-.I stripe_count
-is the number of OSTs to stripe a file over. A
-.I stripe_count
-of 0 means to use the filesystem-wide default stripe count (default 1), and a
-.I stripe_count
-of -1 means to stripe over all available OSTs. The
-.I stripe_size
-is the number of bytes to store on each OST before moving to the next OST. A
-.I stripe_size
-of 0 means to use the filesystem-wide default stripe_size (default 1MB). The
-.I start_ost_index
-is the OST index (starting at 0) on which to start striping for this file. A
-.I start_ost_index
-of -1 allows the MDS to choose the starting index and it is strongly
-recommended, as this allows space and load balancing to be done by the MDS as
-needed. The
-.B -o
-option is used to specify the exact stripe layout on the file system.
-.I ost_indices
-is a list of OSTs referenced by their indices, which are specified in decimal
-or hex form and can be obtained using the
-.B lfs osts
-command. The list format consists of individual OST indices and index ranges
-separated by commas, e.g. 1,2-4,7. The
-.B -o
-option may be specified multiple times to stripe across the union of all listed
-OSTs. If the
-.B -c
-option is combined with
-.B -o
-the
-.I stripe_count
-must agree with the number of OSTs in
-.IR ost_indices .
-If the
-.B -i
-option is combined with
-.B -o
-the
-.I start_ost_index
-must be in the OST list, and it will be used as the index on which to start
-striping the file. Otherwise the striping will occur in the order specified in
-.IR ost_indices .
-The
-.I poolname
-is the name of a predefined pool of OSTs (see
-.BR lctl (8))
-that will be used for striping. The
-.IR stripe_count ,
-.IR stripe_size ,
-and
-.I start_ost_index
-will be used as well; the
-.I start_ost_index
-must be part of the pool or an error will be returned.
-.TP
-.B setstripe -d
-Delete the default striping on the specified directory.
-.TP
.B fid2path [--link <linkno>] <fsname|rootpath> <fid> ...
Print out the pathname(s) for the specified \fIfid\fR(s) from the filesystem
mounted at \fBrootpath\fR or named \fBfsname\fR. If a file has multiple
or the OSTs in
.IR filesystem.pool .
.TP
-.B quota [-q] [-v] [-o obd_uuid|-i mdt_idx|-I ost_idx] [-u|-g <uname>|<uid>|<gname>|<gid>] <filesystem>
-To display disk usage and limits, either for the full filesystem, or for objects on a specific obd. A user or group name or an ID can be specified. If both user and group are omitted quotas for current uid/gid are shown. -v provides more verbose (with per-obd statistics) output. -q disables printing of additional descriptions (including column titles).
+.B quota [-q] [-v] [-o obd_uuid|-i mdt_idx|-I ost_idx] [-u|-g|-p <uname>|<uid>|<gname>|<gid>|<projid>] <filesystem>
+To display disk usage and limits, either for the full filesystem, or for objects on a specific obd. A user or group name or an ID can be specified. If user group and project are omitted quotas for current uid/gid/projid are shown. -v provides more verbose (with per-obd statistics) output. -q disables printing of additional descriptions (including column titles).
.TP
-.B quota -t <-u|-g> <filesystem>
-To display block and inode grace times for user (-u) or group (-g) quotas
+.B quota -t <-u|-g|-p> <filesystem>
+To display block and inode grace times for user (-u) or group (-g) or project (-p) quotas
.TP
.B quotacheck [-ugf] <filesystem> (deprecated as of 2.4.0)
To scan the specified filesystem for disk usage, and create or update quota files. Options specify quota for users (-u) groups (-g) and force (-f). Not useful anymore with servers >= 2.4.0 since space accounting is always turned on.
.B quotaoff [-ugf] <filesystem> (deprecated as of 2.4.0)
To turn filesystem quotas off. Options specify quota for users (-u) groups (-g) and force (-f). Not used anymore in lustre 2.4.0 where quota enforcement can be turned off (for inode or block) by running the following command on the MGS: lctl conf_param ${FSNAME}.quota.<ost|mdt>=""
.TP
-.B setquota <-u|-g> <uname>|<uid>|<gname>|<gid> [--block-softlimit <block-softlimit>] [--block-hardlimit <block-hardlimit>] [--inode-softlimit <inode-softlimit>] [--inode-hardlimit <inode-hardlimit>] <filesystem>
-To set filesystem quotas for users or groups. Limits can be specified with -b, -k, -m, -g, -t, -p suffixes which specify units of 1, 2^10, 2^20, 2^30, 2^40 and 2^50 accordingly. Block limits unit is kilobyte (1024) by default and block limits are always kilobyte-grained (even if specified in bytes), see EXAMPLES
-.TP
-.B setquota -t [-u|-g] [--block-grace <block-grace>] [--inode-grace <inode-grace>] <filesystem>
-To set filesystem quota grace times for users or groups. Grace time is specified in "XXwXXdXXhXXmXXs" format or as an integer seconds value, see EXAMPLES
-.TP
.B swap_layouts <filename1> <filename2>
Swap the data (layout and OST objects) of two regular files. The
two files have to be in the same filesystem, owned by the same user,
Swapping the layout of two directories is not permitted.
.TP
-.B data_version [-n] <filename>
-Display current version of file data. If -n is specified, data version is read
-without taking lock. As a consequence, data version could be outdated if there
-is dirty caches on filesystem clients, but this will not force data flushes and
-has less impact on filesystem.
-
-Even without -n, race conditions are possible and data version should be
-checked before and after an operation to be confident the data did not change
-during it.
