Other Remarks
~~~~~~~~~~~~~
- eNAS ``nas_quotas`` should not be confused with OpenStack manila quotas.
The former edits quotas for mounted file systems, and displays a
listing of quotas and disk usage at the file system level (by the user,
group, or tree), or at the quota-tree level (by the user or group).
``nas_quotas`` also turns quotas on and off, and clears quotas records
for a file system, quota tree, or a Data Mover. Refer to VMAX eNAS CLI
Reference guide on `EMC support site <http://support.emc.com>`_ for
additional information.
``OpenStack manila quotas`` delimit the number of shares, snapshots etc.
a user can create.
