This bug seems like a likely duplicate of BZ 1305408, but will not mark it as such yet before we are sure.

We will need to get the logs to investigate further, preferably from the time when the stress testing happened that leads to the bug.

Additionally - we would also want _exact_ commands used to do the stress testing as opposed to just descriptions.

Ok so I spent some time digging into the already reported bugs and it seems that this has been reported already:

  https://bugs.launchpad.net/nova/+bug/1427060

The proposed patch:

  https://review.openstack.org/#/c/163177/

seems outdated though, so I'll try to work on a more up-to-date one.

Moving back to ON_DEV, the current plan is to remove duplicate BDMs in 14/R with an online migration before then introducing a new constraint around volume_id and instance_uuid on the table in 15/S. While this doesn't fix the underlying race it will ensure duplicate records are not left in the DB.

Hi,

Is this issue already fixed on a newer version? If yes, since which version?

While this remains something that I'd like to eliminate through a reworking the attach volume flow [1] to automatically create and update BDMs within the API we've not seen any additional hits of this recently and so for the time being we will be closing this out as WONTFIX.
