Both nodes begin the process of fencing their peer before either node actually dies. With ACPI enabled, the call to power down a node begins an orderly shutdown. This allows the node's own fence call to fire off a shutdown of the peer node before it dies (~4 seconds between initial shut down call and node death). Disabling ACPI should help in that the node should instantly power down when the first call to shut down comes in (moral equivalent to pressing and holding the power button). With ACPI, you have to hold the power button for 4 seconds before power off. Without ACPI, the node should instantly power off. -- Digimer E-Mail: digimer@xxxxxxxxxxx Papers and Projects: https://alteeve.com -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
