[...] Basically Ceph support via Cinder is not fully supported. Even if you get the API to work, we don't support lot of operations like moving disks between Ceph and other storage types. This should be improved in 4.3, but we don't have concrete plans yet. k. It also seems not being possible to create a datacenter that only contains ceph storage, as this is of type "Volume" instead of "Data" am I correct?
You can also try other ways to integrate Ceph, like cephfs or Ceph iSCSI gateway. These options are fully supported as they use the existing file and block based capabilities. Using the iSCSI-Gateway from ceph also seemed an intresting alternative (as it also removes the need for an openstack environment just for adding the ceph based storage part in my case). However at least for me it seemed that the openstack integration had been pushed more as "the way to go".
