Snapshots exist in a share from failed NDMP backups.
The snapshots do not seem to be able to be deleted using the BUI and/or CLI.
In an attempt to resolve this situation - try to restart the NDMP service in the BUI or CLI.
Go to configuration service and select ndmp and restart the service :
CLI: configuration services ndmp> disable
CLI: configuration services ndmp> enable
Then try to remove/destroy the snapshots in question.
If above steps fail, engage Oracle customer support.
Customer reported NDMP backup server failed and never notified the ZFSSA.
