Did you ask the cluster to shut down before or after the first resource failed? > The result were a lot of unmanaged resources and the cluster even tried > to promote the MS resource on the other node although the second > instance was neither demoted nor stopped. We seem to loose either way. If we have the cluster block people complain shutdown takes too long. Basically at the point a resource fails and stonith is not configured - shutdown is best-effort. > > Is there any possibility to tune this behavior? > > Even with stonith enabled the cluster would first migrate all resources > that don't depend on the unmanaged(failed) resource away before > executing the stonith, am I right? > > thx & Regards, > Andreas > > > _______________________________________________ > 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://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker > > _______________________________________________ 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://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
