Comment 3 for bug 1849827

Yes - but this is the default: https://github.com/openstack/kolla-ansible/blob/master/ansible/group_vars/all.yml#L868

It does not depend on if ceph is enabled or not.

And even if it would - which of the backends we should enable by default:
https://github.com/openstack/kolla-ansible/blob/ade4f4eeb413a06f57e50bdb5462f8407023feb3/ansible/roles/cinder/templates/cinder.conf.j2#L28-L50

nfs or swift? ;-)

I would say we need a feature named posix filesystem and default to that, or fail if the backend is not defined and default to an empty choice?
