--- upgrade: - | This version of OpenStack Manila has not been tested with Ceph clusters prior to Nautilus. CephFS drivers interact with Ceph clusters via a python binding called "ceph_volume_client". This is being replaced by supplying management operations via the ceph manager interface that was introduced in the Nautilus release of Ceph. So it is advised that you upgrade your Ceph deployment prior to upgrading to Manila's Victoria release.
