The only way it can do replication *is* for a consistency group as a whole, so that feature will be available soonish - if you don't care that Cinder/Openstack knows nothing about the ongoing replication. > I'm not sure if those features belong in Cinder or some new > project for DR. IMO this belongs to Cinder. __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
