-.br
-List the striping information for a given filename or directory tree.
-By default the stripe count, size, and offset will be returned. If you
-only want specific striping information then the options of
-.BR --count ,
-.BR --size ,
-.BR --index ,
-.BR --offset ,
-.BR --layout ,
-or
-.B --pool
-can be used to return only the specific fields.
-.br
-If the
-.B --raw
-option is specified, the stripe information is printed without substituting the
-filesystem's default values for unspecified fields. If the striping EA is not
-set, 0, 0, and -1 will be printed for the stripe count, size, and offset
-respectively.
-In the case where you only want details about the files' object id
-information then the
-.B --quiet
-option is used. Additional information available about striping can be
-displayed with
-.BR --verbose .
-The default behavior when a directory is specified is to list the striping
-information for all files within the specified directory (like
-.RB ' "ls -l" ') .
-This can be expanded with
-.B --recursive
-which will recurse into all subdirectories.
-If you wish to get striping information for only the specified directory, then
-.B --directory
-can be used to limit the information, like
-.RB ' "ls -d" ').
-You can limit the returned files to those with objects on a specific OST with
-.BR --obd .

- \fB[--stripe-index|-i start_ost_index] [--pool <poolname>]
- \fB<dirname|filename>\fR
-.br
-To create a new file, or set the directory default, with the specified striping parameters. The
-.I stripe_count
-is the number of OSTs to stripe a file over. A
-.I stripe_count
-of 0 means to use the filesystem-wide default stripe count (default 1), and a
-.I stripe_count
-of -1 means to stripe over all available OSTs. 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
-.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 poolname
-is the name of a predefined pool of OSTs (see
-.B lctl
-) that will be used for striping. The
-.IR stripe_count ,
-.IR stripe_size ,
-and
-.I start_ost_index
-will be used as well; the
-.I start_ost_index
-must be part of the pool or an error will be returned.
-.TP
-.B setstripe -d
-Delete the default striping on the specified directory.

-.B fid2path [--link <linkno>] <fsname|rootpath> <fid> ...
-Print out the pathname(s) for the specified \fIfid\fR(s) from the filesystem
-mounted at \fBrootpath\fR or named \fBfsname\fR. If a file has multiple
-hard links, then all of the pathnames for that file are printed, unless
-\fB--link\fR limits the printing to only the specified link number (starting
-at 0, in no particular order). If multiple fids are specified, but only a
-single pathname is needed for each file, use \fB--link 0\fR.
-.TP
-.B path2fid <path> ...
-Print out the FIDs for the specified \fBpath(s)\fR. If multiple pathnames
-are given, then they will be printed one per line with the path as prefix.
