Comment 1 for bug 1164929

The cinder force-delete help states it will "Attempt forced removal of a volume, regardless of it's state." Key here being the word "Attempt".

Maybe this isn't overly clear and could be improved. Bailing out on the delete if it's attached is not such a bad thing, but we should consider responding sooner in the stack with a helpful message and NOT locking you out with the "deleting" state.
