Delete a NAS Volume Folder
Delete a NAS volume folder if you no longer want to group NAS volumes.
1. Click the Storage view and select a FluidFS cluster.
2. Click the File System tab, expand NAS Volumes and select a NAS volume folder.
3. In the right pane, click Delete. The Delete dialog box appears.
4. Click OK. If the folder contains NAS volumes, they are moved into the (default) root parent folder of the NAS volume folder.
Cloning a NAS Volume
Cloning a NAS volume creates a writable copy of the NAS volume. This copy is useful to test against non-production data sets in a
test environment without impacting the production le system environment. Most operations that can be performed on NAS
volumes can also be performed on clone NAS volumes, such as resizing, deleting, and conguring SMB shares, NFS exports,
snapshots, replication, NDMP, and so on.
The clone NAS volume is created from a snapshot (base snapshot) taken on the original NAS volume (base volume). No space is
consumed by the clone NAS volume until new data is stored or it is modied.
NAS Volume Clone Defaults
The clone NAS volume will have the following default values:
• Has the same size as its base volume, is thin-provisioned, and its reserved space is 0 (and therefore it consumes no space)
• Quota usage is copied from the base snapshot of the base volume
• 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.
• Has the same permissions on folders including the root directory as the base volume
• Has the same security style and access time granularity denitions as the base volume
• 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 getting 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.
• 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.
• 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.
