hi,

agreed let me add some more comments here as a start.

My plan for the Cinder HA session was to start with what we have today 
and compare it with what we propose in the spec.

The spec indeed is currently 'on pause' because of issues affecting some 
backend drivers (Ceph included) when these are deployed in some 
active/active configuration.

Cinder folks have/are working on it and will have a session about their 
new State Machine [1] which should help in this regard, if not fix it 
entirely.

I'm planning to join their session before having ours, so we can sync up 
our planning with Cinder people and update the spec, hopefully for its 
final revision, jointly.
