Comment 6 for bug 1809313

I think Ceph roles are broken since change: https://review.openstack.org/614457 landed.

None of these roles have the InternalApi network by default:

https://github.com/openstack/tripleo-heat-templates/blob/master/roles/CephAll.yaml
https://github.com/openstack/tripleo-heat-templates/blob/master/roles/CephFile.yaml
https://github.com/openstack/tripleo-heat-templates/blob/master/roles/CephObject.yaml
https://github.com/openstack/tripleo-heat-templates/blob/master/roles/CephStorage.yaml

We don't have per-role ServiceNetMap, so anyone deploying Ceph with this patch will end up with an empty string for the IP value in /etc/hosts.
