In the clusternode <device> line for fencing devices, "name" must be the same as "name" in the appropriate <fencedevice> line. 2. In the <fencedevice> line, the "servers" must be listed using the "name" in <clusternode> line. So, for your configuration, the <fencedevice> line should be <fencedevice agent="fence_gnbd" name="gnbd" servers="hotsite-bsb-la-1.com"/> See if this helps. -Ben > > > # cman_tool status > Version: 6.1.0 > Config Version: 18 > Cluster Name: hotsites > Cluster Id: 27589 > Cluster Member: Yes > Cluster Generation: 184 > Membership state: Cluster-Member > Nodes: 2 > Expected votes: 3 > Total votes: 2 > Quorum: 2 > Active subsystems: 8 > Flags: Dirty > Ports Bound: 0 177 > Node name: hotsite-bsb-la-1.com > Node ID: 1 > Multicast addresses: 239.192.107.49 > Node addresses: 10.65.13.30 > > > Thanks > > -- > Tiago Cruz > http://everlinux.com > Linux User #282636 > > > -- > Linux-cluster mailing list > Linux-cluster@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
