Administrator Guide

• Quota rules have the default denitions (as with a new NAS volume). Directory quotas have the same denitions as the base volume at
the time of the snapshot.
• The volumes have the same permissions on folders (including the root directory) as the base volumes.
• The volumes have the same security style and access time granularity denitions as the base volumes.
• No SMB shares, NFS exports, or snapshot schedules are dened.
NAS Volume Clone Restrictions
The following restrictions exist with clone NAS volumes:
• You cannot create a clone NAS volume of a clone NAS volume (nested clones) unless a clone NAS volume is replicated to another
FluidFS cluster and then cloned.
• You cannot delete a base volume until all of its clone NAS volumes have been deleted.
• A snapshot cannot be deleted as long as clone NAS volumes are based on it.
• Restoring to an older snapshot fails if it would result in a base snapshot being deleted.
• You can replicate a clone NAS volume only after the base volume is replicated. If the base snapshot in the base volume is removed, and
a clone NAS volume exists on the replication target FluidFS cluster, replication between NAS volumes will stop. To resume replication,
the cloned NAS volume on the target FluidFS cluster must be deleted.
• You cannot create a clone NAS volume from a replication source NAS volume snapshot (a snapshot with a name starting with rep_) or
NDMP snapshot. However, you can create a clone NAS volume of a replication target NAS volume.
• Before creating a clone NAS volume, data reduction and the snapshot space consumption threshold alert must be disabled on the base
volume (previously deduplicated data is allowed).
• Data reduction cannot be enabled on a clone NAS volume.
• After a NAS volume is cloned, data reduction cannot be reenabled until all clone NAS volumes have been deleted.
• A clone NAS volume contains user and group recovery information, but not the NAS volume conguration.
• Clone NAS volumes count toward the total number of NAS volumes in the FluidFS cluster.

Create a NAS Volume Clone
Cloning a NAS volume creates a writable copy of the NAS volume.
Prerequisites
• The snapshot from which the clone NAS volume will be created must already exist.
• Data reduction must be disabled on the base volume.
• The snapshot space consumption threshold alert must be disabled on the base volume.
