Dear all, I'm in trouble with adding a new node to an existing cluster of three nodes (so I want to have four), because it somehow doesn't let me access the cluster infrastructure. These 3 nodes were set up as http servers, sharing a GFS2 volume (physical: vg_cluster, logical: lv_cluster) where data is stored. I want to set up the new node to access the same GFS2 volume, with the idea of exporting the data via NFS, so that a remote backup library can be configured to backup nightly the data, by connecting to the new node. I've tried a lot of things, always getting same kind of errors. Running "cman_tool status" on any of the 3 nodes i get: Version: 6.2.0 Config Version: 70 Cluster Name: campusvirtual Cluster Id: 45794 Cluster Member: Yes Cluster Generation: 1136 Membership state: Cluster-Member Nodes: 3 Expected votes: 4 Total votes: 3 Quorum: 3 Active subsystems: 9 Flags: Dirty Ports Bound: 0 11 177 Node name: cev01 Node ID: 2 Multicast addresses: 239.192.178.149 Node addresses: 150.214.243.20 while running "cman_tool status" on the new node: Version: 6.2.0 Config Version: 70 Cluster Name: campusvirtual Cluster Id: 45794 Cluster Member: Yes Cluster Generation: 1124 Membership state: Cluster-Member Nodes: 1
This is the key. The new node can't see the network traffic of the other three. The most likely explanation for this is iptables blocking the traffic.
But check other network connections and settings too - It's almost certainly a network configuration problem. The multicast and node addresses look fine to me.
