<para>The old lfs quota output was very detailed and contained cluster-wide quota statistics (including cluster-wide limits for a user/group and cluster-wide usage for a user/group), as well as statistics for each MDS/OST. Now, <literal>lfs quota</literal> has been updated to provide only cluster-wide statistics, by default. To obtain the full report of cluster-wide limits, usage and statistics, use the <literal>-v</literal> option with <literal>lfs quota</literal>.</para>

<para>Report file system disk space usage or inode usage (with <literal>-i</literal>) of each MDT/OST or a subset of OSTs if a pool is specified with <literal>-p</literal>. By default, prints the usage of all mounted Lustre file systems. Otherwise, if path is specified, prints only the usage of that file system.

<para>If the <literal>--raw</literal> 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.</para>
