booth has been designed with quite a different purpose in mind. A ticket has only two states* and depending on that a resource may be allowed to start (or promote) on the cluster or not. A ticket fails over to another site in case the existing site is not reachable anymore. Or the user defined external program fails. Perhaps you could fiddle with the latter, but I doubt that it'd be of any use in the end. So, the short answer is that booth isn't meant for what you want to achieve here. Thanks, Dejan *) Apart from granted/revoked there's also standby, but that's not relevant here. > > Best regards, > Christian > _______________________________________________ > 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 _______________________________________________ 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
