So I think cinder has fixed this now they have improved state handling.
It moves into the detaching state, which causes the duplicates to fail.

We need to double check this again on master, so marking as invalid for
now, while we wait for a valid repo steps and logs capturing the error
that occurs.

It's possible this is backend specific (cinder and nova) so please give
more details on the repo environment.

Title:
  duplicate detach volume in nova

Status in OpenStack Compute (nova):
  Incomplete

Bug description:
  right now, there are risk that nova will process duplicate detach request. To recur this problem. You can
  1) create a server
  2) attach a volume
  3) detach multi-times
      you can use the bash downside:
      for i in {1..20}
     do
          nova volume-detach server-id volume-id  &
     done

  probably you will see the volume is in detaching for ever.
