Thanks for the information! Really appreciate that it’s communicated properly.
I have a question, I think it’s a little harsh to constraint deployments needing the same release for server and client when The Ceph project itself guarantees backward compatibility. What is the reasoning behind this and will Cinder upstream ensure that upgrade paths between Ceph releases are not broken?
