Mike 1) I am not aware of any problems of initial N-controller setup configuration. Could anyone point me to the bug regarding this problem? 2) Adding of the controller is the same problem as I already pointed - it is related to the cluster lifecycle management which we do not have right now and are really striving hard to (partially-) implement in 5.0 release. As soon as we have controller added - we need to go through all the controllers and fix configuration for: rabbitmq, haproxy, mysql and so on. Thus, we need to split deployment into granular roles and re-run deployment for particular roles. Currently, our roles are far too huge to do this, that's why we need granular deployment feature.
