However, it doesn't provide much benefit without one. It's supposed to use "master-wins" mode if no heuristic is provided to avoid a fence-race - but it currently doesn't provide that guarantee. > Another thing I've noticed (with RHEL4 RHC) is the the quorum disk doesn't > show up in the node list of the first node set up in the cluster, and > doesn't contribute a vote. Anyone have any ideas about that? It's not really a node, and is not reported by CMAN in the nodes list as it is in RHEL5/STABLE2 branches. You can see the votes (assuming each node gets one vote) by looking @ cman_tool status: [root@red cluster]# cman_tool status Protocol version: 5.0.1 Config version: 187 Cluster name: rhel4test1 Cluster ID: 44365 Cluster Member: Yes Membership state: Cluster-Member Nodes: 2 Expected_votes: 3 Total_votes: 3 Quorum: 2 Active subsystems: 4 ... Nodes: 2 but Total_votes: 3 => last vote comes from qdiskd -- Lon -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
