.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.
To list the striping info for a given filename or files in a directory, optionally recursively, for all files in a directory tree: \fB--quiet\fR (don't print object IDs), \fB--verbose\fR (print striping parameters), \fB--recursive\fR (recurse into subdirectories).

.br
To create a new file, or set the directory default, with the specified striping parameters. The
.I stripe-count
is the OST index (base 10, starting at 0) on which to start striping for this file. A
.I start-ost
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
-.I pool-name
+.I pool
is the name of a predefined pool of OSTs (see
.I lctl
) that will be used for striping. The
.B poollist <filesystem>[.<pool>] | <pathname>
List the pools in \fBfilesystem\fR or \fBpathname\fR, or the OSTs in \fBfilesystem.pool\fR
.TP

-To display disk usage and limits, either for the full filesystem, or for objects on a specific obd. A user or group name 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.
+.B quota [-v] [-o obd_uuid|-i mdt_idx|-I ost_idx] [-u|-g <uname>|<uid>|<gname>|<gid>] <filesystem>

.TP
.B quotachown
.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.

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
