Resource must have non-negative score on a node to be started on this node. Pacemaker first selects node for A, then different node for B. This leaves C with negative scores for both nodes. To say anything more transaction snapshot would be helpful. _______________________________________________ Users mailing list: Users@clusterlabs.org https://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
