Right, pacemaker upgrade might not be the biggest problem. I've seen other packages upgrades cause RA monitors to return results like $OCF_NOT_RUNNING or $OCF_ERR_INSTALLED. This of course causes the cluster to react, so I prefer the node standby option :) In this case the pacemaker was trying to stop the resources, the stop action has failed and the upgrading node was killed off by the second node trying to cleanup the mess. The resources should have come up on the second node after that. -- Valentin _______________________________________________ Users mailing list: Users@clusterlabs.org http://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
