Hi,
I've wanted to use ceph storage as a backend for nova, glance and cinder. I've succeded to use ceph for cinder and glance but I couldn't at nova.
I have seen this bug for "Stein" version --->
https://bugs.launchpad.net/nova/stein/+bug/1860990

bugs.launchpad.net
When [DEFAULT]show_multiple_locations option is not set in glance, and both glance and nova use ceph as their backend, with properly configured accesses, nova will fail with the following exception: 2020-01-23 14:36:43.617 8647 ERROR nova.compute.manager [req-8021fd76-d5ab-4a9b-bd17-f5eb4d4faf62

After that, I've entered the nova-compute pod and I've run below commands;
apt install python-rbd
apt install python3-rbd
But it didn't work. I've gotten same error.
A solution must be on the K8s side.

Do
you have any of ideas about that?
