Is the right module loaded? Did you change the res file? Did the host names change in any way? Did you actually specify a node-id in the res file? All in all the quick way out would most likely be: - double check the right drbd9 module is loaded. - add a node-id for every host to the res file on all nodes. If possible the same ID/host combination on all nodes :). - create-md on all sides - start an initial sync or if you are certain enough that everything was fine, skip the initial sync.
