Re: Unmanaged snapshots

Unmanaged snapshot might came from:

1) Some snapshots which originally created by volume collection; but then VC were removed later hence those snapshots didn't get removed (retention) and became orphaned snapshots.

2) While customer extend the volume size, system will automatically create a snapshot (name start with "Nss") for recovery purpose; in case something goes wrong at file system level....  Those kind of system snapshot will not be clean up automatically and requires administrator to remove that as the normal house keeping task.

 

To remove those unmanaged snapshot, please reference the thread below:
