Yup! Remember to change 'locking_type' to '3'. If you're not using LVM under the cluster, and I strongly recommend this, then also set 'fallback_to_local_locking' to '0'. This way, if the node is out of the cluster, it will not try to access the clustered LVM at all. digimer PS - Please keep replies on the list, it helps others being able to find this in the archives later. -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education? _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
