Hi guys,

most of things of cluster in Fedora has been changed, comparing with RHEL5.

We are using corosync for membership now, and (IIRC) openais is must to maintain some compatibility with APIs. CMAN still controls the quorum system, and cluster.conf continues to be the configuration file.

If you want to learn more about how to create a cluster using Fedora 13, I believe a good idea is to learn about corosync at http://www.corosync.org, and cman at http://sources.redhat.com/cluster/wiki/
