Comment 3 for bug 1543718

The test covers unsupported case "controller nodes have an additional 'ceph-osd' role", see https://docs.mirantis.com/openstack/fuel/fuel-6.1/release-notes.html#storage-technologies-issues. Note, it should be put to the reference architecture or at least reappear to the 7.0 release notes, it is not there now!
