You can turn off automatic aggregate Snapshot copy creation for a particular aggregate, using the same nosnap option that you would for volume Snapshot copy. Disabling automatic aggregate Snapshot copy creation reclaims the free space used for the aggregate Snapshot reserve. However, you are advised to leave automatic aggregate Snapshot copy creation enabled, in case you need any low-level file system repair.
If you have a MetroCluster configuration or if you are using RAID SyncMirror, ensure that no creation of aggregate Snapshot copies is scheduled. If Snapshot creation has been scheduled, an error message is displayed, advising you to turn off scheduled creation of aggregate Snapshot copies to reduce the chances of running out of space for aggregate Snapshot copies.
aggr_name is the name of the aggregate for which you want to disable automatic Snapshot copy creation.
