After NetApp normally deletes the Vol, the Aggr space will not be deleted immediately by default. It will be kept in the recovery queue for 12 hours. If you need to delete it immediately, you need to manually delete the volume from the recovery queue.
In the CIFS/NFS scenario, first unmount the volume combined with the path.
After confirming that there is no abnormality, the volume will be offline.
