Hi all Today, my cluster crashed, then I have several questions to ask . - First of all, is there a kind of "heartbeat" on a quorum disk ? If yes, it means, I have two heartbeat on my cluster, one by the quorum, second one by a network link. Is it right ? - How to set the heartbeat link in my cluster conf ? Is the "monitor link" is a heartbeat when I set an IP adress to my service ? I have 2 cards just for the heartbeat network and I have two others cards for another vlans. - I use mkqdisk to configure my quorum disk. My two nodes were able to see it (I used mkqdisk -L on each node). My cluster was quorate. But when I killed my first node, the second one didn't take the service and the cluster told me it was inquorate ( Cluster is not quorate. Refusing connection. Error while processing connect: Connection refused). Then service was down and cluster was strange. ccsd and qdiskd were still running. I relocated service manually and everything was right. Service moved to a node to another one without any problem. Well .. thanks for your help. mog -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
