image snapshot creates copy of base image only

We've recently upgraded openstack using Ubuntu MAAS and Juju for provisioning and deployment. All services are deployed on Ubuntu Xenial.

When a user creates an image snapshot, the resulting snapshot image is only a copy of the server's original base image. It doesn't appear that the image delta is being applied to the newly created snapshot. Ceph is used as the store for both Glance and Cinder and Nova compute uses both local storage as well as Ceph.

Any suggestions on what might be happening or be misconfigured in our current setup?

Thanks in advance, Ross

Show how you configured the Cinder, Glance and Nova backends.

Normally, images in Ceph should be in raw format; in other words, there should be no base image. See the 2nd red warning on http://docs.ceph.com/docs/master/rbd/....
