Do not take it as definitive answer, but cl-broker-vips cannot run unless both other resources are started. So if you compute closure of all required transitions it looks rather logical. Having cl-broker-vips started while broker is still stopped would violate constraint. _______________________________________________ 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
