Title:
Swapping volume can't been swap again
Status in OpenStack Compute (nova):
Fix Released
Bug description:
If we had two volume, one is attached by a instance, and the other is still
available.
Due to https://bugs.launchpad.net/nova/+bug/1489744, those volumes will stay
in wrong status.
It will swap successful after fix the issue.
Volumes will be available and in-use status.
But when I try to swap in-use volume with other available volume.
Nova compute will throw following exception:

In first swap, nova will save serial with old volume id in block device
mapping.
Therefore nova will try to find block device mapping through old volume id at

It had been change to new volume id, so nova will raise no bdm not found.
