I am also running a 3 nodes cluster with qdisk. Before, my node1 , node2 and nod3 has 1, 1, 2 votes and qdisk had 2. I ran into the same problem as u are having now. Then I change the votes from 2 to 1 to node 3 and added a vote to qdisk . Now it is running fine. I don't know what happed before. I have tested a lot but didnot succeeded. Now my, interval = 1 and tko=10 in my case. Paras. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
