Hi As said before, I'm trying for the first time to add a quorum disk on my two nodes cluster. Finally, I've set parameters as below : <quorumd interval="1" tko="10" votes="1" log_level="9" log_facility="local4" status_file="/tmp/qdisk_status" label="CS4QUORUMDISK"> </quorumd> and <clusternode name="node1" votes="1"> and <clusternode name="node2" votes="1"> and <cman expected_votes="3" two_node="0"/> With these parameters values for my two nodes cluster, I have to launch the Cluster Suite on both nodes, it can't be launched on one node only because cman detects "not quorate". Is there a way to avoid this ? to be able to launch CS4 only on one side ? Could somebody give me the advised values for such a two-nodes cluster ? By the way, how can I be shure that quorum disk is really used , where can I see traces ? (I see nothing in syslog) Thanks a lot for your help Alain Moullé -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
