NAS Volume Clone Restrictions
The following restrictions apply to cloned 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 there are clone NAS volumes 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 or NDMP snapshot.
However, you can create a clone NAS volume of a replication target NAS volume.
• Prior to 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.
• Once a NAS volume is cloned, data reduction cannot be re‐enabled until all clone NAS volumes have
been deleted.
• A clone NAS volume contains user and group recovery information, but not the NAS volume
configuration.
• Clone NAS volumes count towards the total number of NAS volumes in the FluidFS cluster.
Managing NAS Volume Clones
View, create, and delete NAS volume clones.
Viewing NAS Volume Clones
View the current NAS volume clones.
1. Click the NAS Volumes tab on the left.
2. Click the All NAS Volumes tab on the top.
3. In the All NAS Volumes pane, click in the row of the volume whose NAS volume clones you want
to view.
4. Click View Details.
5. Click the Snapshots tab on the top.
The cloned volumes are displayed in the Cloned NAS Volumes pane.
Creating a NAS Volume Clone
Cloning a NAS volume creates a writable copy of the NAS volume.
• There must be an existing snapshot from which the clone NAS volume will be created.
• Data reduction must be disabled on the base volume.
