Hi I have also faced similar error, raised this as bug but at last resolved this in two ways. 1. Network Bonding(more reliable network) 2. Updated fence package. This worked for my setup, I am using HP-iLO as fencing device.

I think I have found a design-error in the CS4. If you boot up one node(1) and this node(1) cant reach the other node(2) node(1) trys to fence node(2). This is fine... but if the fencing fails, node(1) starts his services via rgmanager without to be shure that the other node is not working. volia and you have a splitt-brain problem. any solution for this? any answer aka "use more hardware" is not a solution I think. cu falk -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster =========================================================== Privileged or confidential information may be contained in this message.
