Andrew, Thanks for the clarification - that worked !
So I now have two test setups, one with pacemaker/cman/corosync and one with just pacemaker/corosync as described in the clusters from scratch document. Which is the better architecture for a cluster I am installing mid year ? From what I can see the cman setup does not allow for redundant corosync rings nor crossover cables(ie https://access.redhat.com/knowledge/articles/40051 ) while pacemaker/corosync does not have this restriction. For a simple two-node drbd cluster cman pacemaker/corosync(or heartbeat) looks like a better choice. Am I reading this correctly ? Also from what I've read it looks like the official redhat clustering is moving to pacemaker/corosync ... when ?

I made a mistake. The line: [ONE] # ccs -f /etc/cluster/cluster.conf --addfencedev pcmk-redirect agent=fence_pcmk should have been [ONE] # ccs -f /etc/cluster/cluster.conf --addfencedev pcmk agent=fence_pcmk Sorry. > > Running rhel 6.3 : > > [root@hatest1 /]# rpm -q pacemaker cman ccs resource-agents > pacemaker-1.1.7-6.el6.i686 > cman-3.0.12.1-32.el6_3.2.i686 > ccs-0.16.2-55.el6.i686 > resource-agents-3.9.2-12.el6_3.1.i686 > [root@hatest1 /]# > > Thanks > > > David Livingstone > > _______________________________________________ > 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
