.B check
Display the status of MDS or OSTs (as specified in the command) or all the servers (MDS and OSTs)
.TP
-.B df
-Report filesystem disk space usage or inodes usage of each MDT/OST. Can limit
-the scope to a specific OST pool
+.B df [-i] [-h] [--pool|-p <fsname>[.<pool>] [path]
+Report filesystem disk space usage or inodes usage (with \fB-i\fR) of each
+MDT/OST, or a subset of OSTs if a pool is specified with \fB-p\fR. By default
+print the usage of all mounted Lustre filesystems, otherwise if \fBpath\fR is
+specified print only the usage of that filesystem. If \fB-h\fR is given, the
+output is printed in \fIh\fRuman readable format, using SI base-2 suffixes
+for \fBM\fRega-, \fBG\fRiga-, \fBT\fRera-, \fBP\fReta-, or \fBE\fRxabytes.
.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). 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.
