Deleting Nutanix Files Previous Version Snapshots

Nutanix Files can be configured for self-service restore. When a share is configured for SSR, the FSVM's will take internal snapshots of the shares. These snaps will consume storage, and may prevent free space from opening up when data has been removed from the share. To resolve this, you will need to use several afs commands to reclaim the storage and remove the snapshot.

1. Connect via SSH to any FSVM in the Nutanix Files cluster. Be sure to connect using an IP from the Storage Network and not the Client network.
2. List the snapshots for the share. The share name is case sensitive.

nutanix@FSVM$ afs snapshot.list share_name=<share_name>
#1:	Snapshot Name: afs-auto-snap_weekly-2020-03-15-0700
	Snapshot UUID: 05e65a80-36df-45a7-9032-87fa7296ef9a  <<==== Snapshot UUID
	Share Name: <sharename>	                             				      
	Type: SSR

#2:	Snapshot Name: afs-auto-snap_daily-2020-03-17-0700
	Snapshot UUID: f4d7d268-a90b-4288-b6c5-6fabfe264c0d
	Share Name: <sharename>
	Type: SSR

3. Identify the total amount of storage being consumed by the snapshot.

nutanix@FSVM$ afs snapshot.reclaimable_space <uuid_start>:<uuid_end>

4. Remove the snapshots.
