+.B data_version [-nrw] <filename>
+Display the current version of file data. If -n is specified, the data version
+is read without taking a lock. As a consequence, the data version could be
+outdated if there are dirty caches on filesystem clients, but this option will
+not force data flushes and has less of an impact on the filesystem. If -r is
+specified, the data version is read after dirty pages on clients are flushed. If
+-w is specified, the data version is read after all caching pages on clients are
+flushed.
+
+Even with -r or -w, race conditions are possible and the data version should be
+checked before and after an operation to be confident the data did not change
+during it.
+
+The data version is the sum of the last committed transaction numbers of all
+data objects of a file. It is used by HSM policy engines for verifying that file
+data has not been changed during an archive operation or before a release
+operation, and by OST migration, primarily for verifying that file data has not
+been changed during a data copy, when done in non-blocking mode.

 .B quotaoff [-ugf] <filesystem> (deprecated as of 2.4.0)
 To turn filesystem quotas off.  Options specify quota for users (-u) groups (-g) and force (-f). Not used anymore in lustre 2.4.0 where quota enforcement can be turned off (for inode or block) by running the following command on the MGS: lctl conf_param ${FSNAME}.quota.<ost|mdt>=""

-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
