Public bug reported:
[Env]
Ubuntu 14.04
OpenStack Icehouse
[Descrition]
I am usting pdb to debug nova attach_volume operation, due to the reason that the command is timeout, the volume failed to be attached to the instance, however, in the nova db, the attachment device is already recorded other than fallback, which is completely not right from user's perspective.
For example, nova instance '1' shows "os-extended-
volumes:volumes_attached | [{"id":
"3c8205b9-5066-42ea-9180-601fac50a08e"}, {"id":
"3c8205b9-5066-42ea-9180-601fac50a08e"}, {"id":
"3c8205b9-5066-42ea-9180-601fac50a08e"}, {"id":
"3c8205b9-5066-42ea-9180-601fac50a08e"}] |" even if the volume
3c8205b9-5066-42ea-9180-601fac50a08e is actually available.
I am concerning there are some situations nova attach_volume would fail
in the middle procedure which would have this issue as well, is it
better to delay the db persistent step after the device is really being
attached?
