Comment 1 for bug 1302332

This looks like a tempest test that failed because it tried to remove a cinder volume while that cinder volume was in use. This is either a bug in cinder (didn't stop using the volume before it attempted to delete it) or the tempest test (didn't stop using the volume before telling cinder to delete it). I do not think this is an infrastructure bug. If you have evidence to the contrary please update the bug and I can triage this further with regard to it being an infrastructure bug.
