It's been a while since I tested it (couldn't use it because of issues with GFS2), but yes it worked. Don't edit corosync.conf, all corosync config is handled in cman's cluster.conf. I believe you need to specify the '<altname />' element for the second ring. If you still have trouble, let me know and I'll see if I can find my old notes. -- Digimer Papers and Projects: https://alteeve.com/w/ "I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops." - Stephen Jay Gould _______________________________________________ Users mailing list: Users@clusterlabs.org http://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
