+.SH NAME
+lfs getdirstripe \- list the striping pattern of a given directory.
+.SH SYNOPSIS
+.B lfs getdirstripe
+[\fIOPTION\fR]... \fIDIR\fR...
+.SH DESCRIPTION
+Get the striping pattern information of directories. This lfs utility is
+similar to
+.B lfs getstripe
+, but is used to get directory striping pattern.
+.BP lfs
+.SH OPTIONS
+.TP
+.B \-c, \-\-stripe-count
+Only show the stripe count of the directory.
+.TP
+.B \-i, \-\-stripe-index
+Only show the stripe index of the directory.
+.TP
+.B \-R, \-\-raw
+The striping information is printed without substituting the
+filesystem's default values for unspecified fields. If the striping EA is not
+set, 0, and -1 will be printed for the stripe count, and offset respectively.
+.TP
+.B \-q, \-\-quiet
+Only show the details of the sub-striped directory FID information.
+.TP
+.B \-v, \-\-verbose
+Additional information will be shown with this option.
+.TP
+.B \-r, \-\-recursive
+The default behavior when a directory is specified is to list the striping
+information for all sub-directories within the specified directory. This
+can be expanded with --recursive, which will recurse into all subdirectories.
+.TP
+\fB\-O\fR, \fB\-\-obd\fR=\fIFSNAME-MDTnnnn_UUID\fR
+Limit the returned directories to those with objects on a specific MDT,
+whose uuid is
+.I FSNAME-MDTnnnn_UUID.
+.SH EXAMPLES
+.TP
+.B $ lfs getdirstripe -O lustre-MDT0001_UUID -r /mnt/lustre/dir1
+List the striping information of sub-directories, that are located on MDT1,
+under /mnt/lustre/dir1.
+.SH AVAILABILTY
+The lfs getdirstripe command is part of the Lustre filesystem.

+.SH NAME
+lfs setdirstripe, mkdir \- set striping pattern of a directory.
+.SH SYNOPSIS
+.B lfs setdirstripe
+[\fIOPTION\fR]... \fIDIR\fR...
+.br
+.SH DESCRIPTION
+Create a striped directory with specified striping pattern. This lfs utility
+is similar to
+.B lfs setstripe
+, but is used to create striped directory.
+.B lfs mkdir
+is an alias for this command.
+.SH OPTIONS
+.TP
+\fB\-c\fR, \fB\-\-count\fR=\fICOUNT\fR
+Stripe over
+.I COUNT
+MDTs.
+.TP
+\fB\-i\fR, \fB\-\-index\fR=\fISTART_MDT_INDEX\fR
+Stripe from the MDT, whose index is
+.I START_MDT_INDEX.
+.TP
+\fB\-t\fR, \fB\-\-hash\-type\fR=\fIHASH_TYPE\fR
+the hash_type of the striped directory.
+.RS 1.2i
+.TP
+.B fnv_1a_64
+Fowler-Noll-Vo (FNV-1a) hash algorithm. This provides
+reasonably uniform, but not cryptographically strong,
+hashing of the filename. (default)
+.TP
+.B all_char
+Sum of ASCII characters modulo number of MDTs. This
+provides weak hashing of the filename, and is suitable
+for only testing or when the input is known to have
+perfectly uniform distribution (e.g. sequential numbers).
+.RE
+.TP
+.B \-D, \-\-default_stripe
+Set the default striping pattern of the directory. Newly created
+sub-directories will use the new default striping pattern,
+but existing sub-directories will not be affected. The newly
+created sub-directories will also inherit the current default
+striping pattern. Only default stripe count is supported for now.
+.TP
+\fB\-m\fR, \fB\-\-mode\fR=\fIMODE\fR
+Set the file access mode of the new directory to the specified
+numeric value (typically octal) as specified in
+.BR chmod (1),
+and is not affected by the current
+.BR umask (1p).
+.SH NOTE
+.PP
+The "lfs setdirstripe" command is only executable by root unless
+"mdt.*.enable_remote_dir_gid" is set via "lctl set_param" to be either a
+non-zero GID to limit it to a single group (e.g. "operator" or "admin"),
+or "-1" to allow any group to create remote directories.
+
+The root of the file system is on MDT0000, and directories and files inherit the
+MDT of their parent directory unless a different MDT is specified with this
+command.
+
+By default, only directories on MDT0000 can contain directories that are not on
+the same MDT. However, if "mdt.*.enable_remote_dir" is set non-zero on an MDT
+then it will allow creating remote directories that have parents other than
+MDT0000. This is restricted to avoid creating directory trees that have
+intermediate path components on a series different MDTs and become unavailable
+if any of the intermediate MDTs are offline.
+.SH EXAMPLES
+.TP
+.B $ lfs setdirstripe -c 2 -i 1 -t all_char /mnt/lustre/dir1
+This creates a directory striped on two MDTs, whose first stripe is on
+.B MDT0001
+(MDT index 1), and whose hash type is
+.BR all_char .
+.SH BUGS
+Default stripe cannot be deleted once it is set.
+.SH AVAILABILITY
+The lfs setdirstripe command is part of the Lustre filesystem.
