As an example using my below config: Node1 is running service1, node2 is running service2, etc, etc, node5 is spare and available for the relocation of any failover domain / cluster service. If I go into the APC PDU and turn off the electrical port to node1, node2 will fence node1 (going into the APC PDU and doing and off, on on node1's port), this is fine. Works well. When node1 comes back up, then it shuts down service1 and service1 relocates to node5. Now if I go in the lab and literally pull the plug on node5 running service1, another node fences node5 via the APC - can check the APC PDU log and see that it has done an off/on on node5's electrical port just fine. But I pulled the plug on node5 - resetting the power doesn't matter. I want to simulate a completely dead node, and have the service relocate in this case of complete node failure. In this RHEL5.4 cluster, the service never relocates. I can similate this on any node for any service. What if a node's motherboard fries? What can I set to have the remaining nodes stop waiting for the reboot of a failed node and just go ahead and relocate the cluster service that had been running on the now failed node?
