Public bug reported:

Steps:
1. Create VM
2. Create volume
3. Attach volume to VM
4. Pause VM
5. Detach volume
6. Attach volume back (without unpausing the VM)

What happens is the volume enters the state "attaching" for a while but
then becomes "available" again without being "in-use". Nova-compute and
cinder-volume logs report nothing about it even with debug enabled

Nova version: 2014.2.1
I am aware of the bug https://bugs.launchpad.net/nova/+bug/1242366 but this is a bit different case and the release we use already have the fix installed

** Affects: nova
     Importance: Undecided
         Status: New
