Paras, A curiosity question: How do you make sure that your storage will survive failure of *either* of your site without loss of data and continuity of service? What storage configuration are you using? Thanks and regards,
From: linux-cluster-bounces@xxxxxxxxxx [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of Paras pradhan Hi, My GFS2 linux cluster has three nodes. Two at the data center and one at the DR site. If the nodes at DR site break/turnoff, all the services move to DR node. But if the 2 nodes at the data center lost communication with the DR node, I am not sure how does the cluster handles the split brain. So I am looking for some recommendation in this kind of scenario. I am usig Qdisk votes (=3) in this case. -- Here is the cman_tool status output. - Version: 6.2.0 Config Version: 74 Cluster Name: vrprd Cluster Id: 3304 Cluster Member: Yes Cluster Generation: 1720 Membership state: Cluster-Member Nodes: 3 Expected votes: 6 Quorum device votes: 3 Total votes: 6 Quorum: 4 Active subsystems: 10 Flags: Dirty Ports Bound: 0 11 177 Node name: vrprd1.hostmy.com Node ID: 2 Multicast addresses: x.x.x.244 Node addresses: x.x.x.96 -- Thanks!
