.SH DESCRIPTION
.B lfs
.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.
.TP
+.B getname [-h]|[path ...]
+Report all the Lustre mount points and the corresponding Lustre filesystem
+instance. If one or more \fBpath\fR entries are provided, then only the
+Lustre instance for these mount points is returned. If the path given is not on
+a Lustre instance 'No such device' is reported.
+.TP
.B osts
.RB [ path ]
List all the OSTs for all mounted filesystems. If a \fBpath\fR is provided
You can limit the returned files to those with objects on a specific OST with
.BR --obd .

.br
To create a new file, or set the directory default, with the specified striping parameters. 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
+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
.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 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.
