Comment 30 for bug 1928690

Albert, I found a very relevant bug: https://bugs.launchpad.net/kolla-ansible/+bug/1934145. Fix is here: https://review.opendev.org/c/openstack/kolla-ansible/+/798851. I'm not sure if it's exactly the same issue, but does affect your workaround, in that you will have to set ceph_nova_user back to nova once the fix merges.
