I think you're missing brackets... ie. order stop_order inf: ( apache_group:stop \ tomcat_group:stop \ primary_group:stop ) > > property $id="cib-bootstrap-options" \ > dc-version="1.0.8-042548a451fce8400660f6031f4da6f0223dd5dd" \ > cluster-infrastructure="openais" \ > expected-quorum-votes="2" \ > stonith-enabled="false" \ > no-quorum-policy="ignore" \ > symmetric-cluster="true" > rsc_defaults $id="rsc-options" \ > resource-stickiness="100" > > > > _______________________________________________ > 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
