Thanks Andrew,Is there any possibility to move back manualy a part of the ClusterIP resource (for example ClusterIP:1) to the other node ? Or is it just impossible with this version ?
crm_verify give me the following output : crm_verify[22555]: 2011/03/10_13:49:00 ERROR: clone_rsc_order_lh: Cannot interleave clone ProxyIP and HttpProxyClone because they do not support the same number of resources per node crm_verify[22555]: 2011/03/10_13:49:00 ERROR: clone_rsc_order_lh: Cannot interleave clone HttpProxyClone and ProxyIP because they do not support the same number of resources per node Many thanks, Regards, -- Charles KOPROWSKI _______________________________________________ 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
