I see... This is kind of complicated. If a migration is interrupted, I don't think it is safe for pacemaker to have any implied assumptions about the state of the resource. We might need to have the pengine issue a re-probe in this situation. Any chance you can share your pengine transition files? Making a crm_report for the time frame the issue occurred in would gather this information for you. -- Vossel > > > Ciao > Andi > > _______________________________________________ > 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
