I had a chat with a Nova developer who pointed me to the following patch
at https://review.openstack.org/#/c/84755/ , recently merged in Havana
and included in the latest RDO Havana packages. Resize specifically is
one of the actions affected by this bug, you might want to check that
you're running the latest packages on your Havana node(s) and see if
this might help to resolve the problem?
