DESCRIPTION
nas_quotas 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 turns quotas on and off, and clears quotas records for a
file system, quota tree, or a Data Mover. When a Data Mover is
specified, the action applies to all mounted file systems on the Data
Mover.
CAUTION
!
Quotas should be turned on (enabled) before file systems go into a
production environment. Enabling (or disabling, or clearing)
quotas in a production environment is time consuming and the
process may disrupt file system operation. CIFS clients are
disconnected during these events and NFS clients receive a
message that the server is not responding.
However, once enabled,
quotas can be changed at any time without impact.
