Delete a Storage Class
Admins can also delete storage volumes. To delete a volume, all storage volumes attached to the volume must first be deleted.
$ fuzzball storage class delete af0644ef-ab71-3677-9409-473847af3925
If volumes are still attached to the storage class, an error will be returned:
could not delete storage class af0644ef-ab71-3677-9409-473847af3925: volumes still attached to it
