+.B setquota <-u|-g> <uname>|<uid>|<gname>|<gid> [--block-softlimit <block-softlimit>] [--block-hardlimit <block-hardlimit>] [--inode-softlimit <inode-softlimit>] [--inode-hardlimit <inode-hardlimit>] <filesystem>
+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
+.TP
+.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 swap_layouts <filename1> <filename2>
+Swap the data (layout and OST objects) of two regular files. The
+two files have to be in the same filesystem, owned by the same user,
+reside on the same MDT and writable by the user.
+
+Swapping the layout of two directories is not permitted.
+.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 As a consequence, data version could be outdated if there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.
+.TP
+.B mkdir <--index|-i mdt_index> <dir>
+Allocate a new directory on a specified MDT.
+
+The "lfs mkdir" 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.
+.TP
+.B --version
+Output the build version of the lfs utility. Use "lctl lustre_build_version" to get the version of the Lustre kernel modules
