+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
+hard links, then all of the pathnames for that file are printed, unless

.B quota -t <-u|-g> <filesystem>
To display block and inode grace times for user (-u) or group (-g) quotas
.TP
-.B quotachown
-To change files' owner and group on OSTs of the specified filesystem
-.TP
-.B quotacheck [-ugf] <filesystem>
-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)
+.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.
.TP
-.B quotaon [-ugf] <filesystem>
-To turn filesystem quotas on. Options specify quota for users (-u) groups (-g) and force (-f)
+.B quotaon [-ugf] <filesystem> (deprecated as of 2.4.0)
+To turn filesystem quotas on. Options specify quota for users (-u) groups (-g) and force (-f). Not used anymore in lustre 2.4.0 where quota enforcement must be enabled via conf_param (e.g. lctl conf_param ${FSNAME}.quota.<ost|mdt>=<u|g|ug>)
.TP
-.B quotaoff [-ugf] <filesystem>
-To turn filesystem quotas off. Options specify quota for users (-u) groups (-g) and force (-f)
-.TP
-.B quotainv [-ug] [-f] <filesystem>
-Clear quota files (administrative quota files if used without -f, operational quota files otherwise), all of their quota entries, for (-u) users or (-g) groups; after quotainv one must use quotacheck before using quotas. DO NOT USE THIS COMMAND UNLESS YOU REALLY KNOW WHAT IT DOES. IT IS MAINLY FOR INTERNAL PURPOSES.
+.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>=""

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
.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

+.B swap_layouts <filename1> <filename2>
+Swap the data (layout and OST objects) of two regular files. The

+Swapping the layout of two directories is not permitted.

.B data_version [-n] <filename>
Display current version of file data. If -n is specified, data version is read

Set grace times for user quotas: 1000 seconds for block quotas, 1 week and 4 days for inode quotas
