Public bug reported: Description =========== The second and any future attempts to swap volumes using volume-update fail due to a BDM lookup failure using the original volume id (see Logs & Configs for an example).
A previous attempt to fix this was made in bug#1490236 and reverted by bug#1625660. Steps to reproduce ================== - Boot an instance - Create multiple volumes - Attach a single volume - Swap the attached volume with one that is unattached via nova volume-update. - Swap the attached volume with one that is unattached via nova volume-update. Expected result =============== The second attempt succeeds and the new volume is now attached to the instance. Actual result ============= The second attempt fails looking up a BDM with the ID of the original volume. Environment =========== 1. Exact version of OpenStack you are running.
