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 information for a given filename or directory. By default the stripe count, size, and offset will be returned. If you only want specific striping information then the options of \fB--count\fR,\fB--size\fR,\fB--index\fR or \fB--offset\fR plus various combinations of these options can be used to retrieve only what you want. What pools a file belong to can also be obtained with \fB--pool\fR. In the case where you only want details about the files object id information then the \fB--quiet\fR option is used. Additional information available about striping can be displayed with \fB--verbose\fR. The default behavior of lfs getstripe used to retrieve data about a directory is to list all the contents of that directory. If you wish to inquire only about that directory then \fB--directory\fR,can be used to list directory entries instead of its contents in the same manner as ls -d. This can be expanded with \fB--recursive\fR which will recurse into all subdirectories. You can filter the search to return only files that has a object on a specific OST with \fB--obd\fR.

To create a new file, or set the directory default, with the specified striping parameters. The
-.I stripe-count
+.I stripe_count
is the number of OSTs to stripe a file over. A
-.I stripe-count
+.I stripe_count
of 0 means to use the filesystem-wide default stripe count (default 1), and a
-.I stripe-count
+.I stripe_count
of -1 means to stripe over all available OSTs. The
-.I stripe-size
+.I stripe_size
is the number of bytes to store on each OST before moving to the next OST. A
-.I stripe-size
+.I stripe_size
of 0 means to use the filesystem-wide default stripe size (default 1MB). The
-.I start-ost
-is the OST index (base 10, starting at 0) on which to start striping for this file. A
-.I start-ost
+.I start_ost_index
+is the OST index (starting at 0) on which to start striping for this file. A
+.I start_ost_index
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
is the name of a predefined pool of OSTs (see
-.I lctl
+.B lctl
) that will be used for striping. The
-.I stripe-count, stripe-size, start-ost
+.I stripe_count, stripe_size, and start_ost_index
will be used as well; the
-.I start-ost
+.I start_ost_index
must be part of the pool or an error will be returned.
