Title:
failed nova db migration upgrading from grizzly to havana
Status in Ubuntu Cloud Archive:
New
Status in OpenStack Compute (Nova):
Won't Fix
Bug description:
I recently upgraded a Nova cluster from grizzly to havana. We're using
the Ubuntu Cloud Archive and so in terms of package versions the
upgrade was from 1:2013.1.3-0ubuntu1~cloud0 to
1:2013.2~rc2-0ubuntu1~cloud0. We're using mysql-server-5.5
5.5.32-0ubuntu0.12.04.1 from Ubuntu 12.04 LTS.
After the upgrade, "nova-manage db sync" failed as follows:

I checked that the rest of 185 was applied, bumped the version in the
DB to 185, and a second run of "nova-manage db sync" completed without
incident.
