To create a new file with a specific striping pattern
.TP
.B find
-To list the extended attributes for a given filename or files in a directory or recursively for all files in a directory tree. It can also be used to list the files that have objects on a specific OST.
+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). The option \fB--maxdepth\fR allows 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 and null character correspondingly. Using one of these options works in the new (filename only) mode.
+.TP
+.B find
+To list the striping info for a given filename or files in a directory or recursively for all files in a directory tree use one of the following options: \fB[--quiet|-q] [--verbose|-v] [--recursive|-r]\fR. If one of these options is given find works in old (obsolete, please use getstripe instead) filename and striping mode.
.TP
.B getstripe
-To list the striping pattern for given filename
+To list the striping info for given filename or files in a directory or recursively for all files in a directory tree. It can also be used to list the files that have objects on a specific OST.
+.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)
+.TP
+.B quotaon [-ugf] <filesystem>
+To turn filesystem quotas on. Options specify quota for users (-u) groups (-g) and force (-f)
+.TP
+.B quotaoff [-ugf] <filesystem>
+To turn filesystem quotas off. Options specify quota for users (-u) groups (-g) and force (-f)
+.TP
+.B setquota [-u|-g] <name> <block-softlimit> <block-hardlimit> <inode-softlimit> <inode-hardlimit> <filesystem>
+To set filesystem quotas for users or groups. Limits are specific as blocks and inodes, see EXAMPLES
+.TP
+.B quota [-o obd_uuid] [-u|-g] <name> <filesystem>
+To display disk usage and limits, either for the full filesystem, or for objects on a specific obd. A user or group name must be specified.
+.TP
+.B check
+Display the status of MDS or OSTs (as specified in the command) or all the servers (MDS and OSTs)
+.TP
+.B osts
+List all the OSTs for the filesystem
+.TP
+.B df
+Report filesystem disk space usage or inodes usage of each MDT/OST.

.SH EXAMPLES
.TP
-.B $lfs setstripe /mnt/lustre/file1 131072 0 1
-This creats a file striped on one OST
+.B $ lfs setstripe /mnt/lustre/file1 131072 -1 2
+This creats a file striped on two OSTs with 128kB on each stripe.
+.TP
+.B $ lfs setstripe -d /mnt/lustre/dir
