To enable snapshot quotas

1. To display snapshot quotas, enter the following:

   Storage> snapshot quota list
   FS              Quota      Capacity Limit
   ==              =====      ==============
   fs1             on              1G
   fs2             off              0
   fs3             off              0

2. To enable a snapshot quota, enter the following:

   Storage> snapshot quota on fs_name [capacity_limit]

   fs_name	Specifies the name of the file system.
   capacity_limit	Specifies the number of blocks used by all the snapshots for the file system. Enter a number followed by K, M, G, or T (for kilo, mega, giga, or terabyte). The default value is 0.

3. If necessary, you can disable snapshot quotas. You can retain the value of the capacity limit. To disable a snapshot quota, enter the following:

   Storage> snapshot quota off [fs_name] [remove_limit]

   fs_name	Specifies the name of the file system.
   remove_limit	Specifies whether to remove the capacity limit when you disable the quota. The default value is true, which means that the quota capacity limit is removed. The value of false indicates that the quota is disabled but the value of the capacity limit remains unchanged for the file system.

To destroy a snapshot

• To destroy a snapshot, enter the following:

  Storage> snapshot destroy snapshot_name fs_name

  snapshot_name	Specifies the name of the snapshot to be destroyed.
  fs_name	Specifies the name of the file system from which the snapshot was taken. Snapshots with the same name could exist for more than one file system. In this case, you must specify the file system name.

  Note:

  If you want to destroy a snapshot with active retention period, you have to set a retention date in the past on that snapshot using the storage snapshot retention set command, but you can set a retention period in the past only if you have configured Enterprise lockdown mode.
