So I believe this is the same basic issue that exists between cinder and
nova in the fact that it is assumed the event will happen within a
reasonable amount of time, and if it doesn't... sadness.

Title:
  Race condition in quickly attaching / deleting volumes

Status in Cinder:
  New
Status in OpenStack Compute (Nova):
  Confirmed
Status in Tempest:
  Invalid

Bug description:
  It seems that there is a race condition in the stress
  volume_attach_delete test. It creates VMs and volumes, attaches
  volumes and deletes everything.

  The test is waiting for volumes to be in 'in-use' state before
  deleting VMs. It seems that Nova/Cinder don't have time to register
  volumes as attached in their databases before VMs get deleted. Volumes
  are then left attached to deleted VMs and unable to be deleted.
