Hi In our Mitaka cloud we are currently using Gluster as storage backend for Glance and Cinder. We are now starting the migration to ceph: the idea is then to dismiss gluster when we have done.
I have a question concerning Glance. I have understood (or at least I hope so) how to add ceph as store backend for Glance so that new images will use ceph while the previously created ones on the file backend will be still usable. My question is how I can migrate the images from the file backend to ceph when I decide to dismiss the gluster based storage. The only documentation I found is this one: https://dmsimard.com/2015/07/18/migrating-glance-images-to-a-different-backend/ Could you please confirm that there aren't other better (simpler) approaches for such image migration ? Thanks, Massimo
