Probably the cleanest way is to set record-pending=true (either as an operation default, or just on the start operation you're interested in). Then your command (or a wrapper) could check the CIB for a pending start. A simpler approach would be "crm_resource --wait", which blocks until the cluster is idle. The downside is you might wait for other actions that you don't care about. _______________________________________________ Users mailing list: Users@clusterlabs.org http://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
