Do I need to set the location for those resources?
In general, it depends on the fence-device and agent. If the fence-device can control both nodes, you can drive a cloned resource. In this case the parameters pcmk_host_list and pcmk_host_map, etc. for stonithd might be of interest for you. In your case, I think one device can control a single host only, which means the resource for node 1 should run on node 2 and the one for node 2 should run on node 1. This implies, that you need to set the appropriate location contrains to prevent the situation you described, above. It could be like this: location locIPMI-1 resIPMI-1 -inf: apolo location locIPMI-2 resIPMI-2 -inf: diana Best Regards, Volker _______________________________________________ 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
