Description Lee Yarwood 2021-04-12 10:43:17 UTC

+++ This bug was initially created as a clone of Bug #1907392 +++

Description of problem:

$subject, this is an odd little corner case but if an admin resets the state of an attached volume to available there are no checks within n-api stopping a user from attaching the volume to another instance, regardless of the original bdm record.

Version-Release number of selected component (if applicable):
OSP 17

How reproducible:
Always

Steps to Reproduce:
1. Attach a volume to an instance.
2. Reset the state of the volume to available.
3. Attach the volume to another instance.

Actual results:
The volume is attached to both instances in Nova but a single instance in Cinder.

Expected results:
The second request to attach a volume should be rejected by Nova until the attachment is removed.
