Cluster manual fence

 · I have created a 2 nodes cluster with red hat cluster suite and RHEL ES 4. I configured the fencing method as manual. The problem is that when I power off one node to test it, the fencing does not work, on the log I get: fenced: fencing node "nodename" fenced: fence "nodename" failed This will sh. - the only way –I guess- to get node1 up now is to stop the cluster services from the linux rescue shell command. I'm using the manual_fence since I don’t have any hardware fencing device yet. Also, I configure all the cluster services (ccsd, cman, rgmanager, fenced) to be booting on automatically (chkconfig on). A cluster sometimes detects that one of the nodes is behaving strangely and needs to remove it. This is called fencing and is commonly done with a STONITH resource. Fencing may be defined as a method to bring an HA cluster to a known state.

fence_manual: Fence agent for manual interaction. NOTE This component is not supported for production environments. fence_ack_manual: User interface for fence_manual agent. fence_node: A program which performs I/O fencing on a single node. fence_xvm: I/O Fencing agent for Xen virtual machines. fence_xvmd: I/O Fencing agent host for Xen virtual.

I know that the fence device is required to run RHCS, but I am trying now to finish building the cluster using the manual fence. My questions are.

To align the Cluster Monitor's Manual with the new developments in particular the Is displayed in HT's office, school notice board, wall or fence. These instructions use ip link set eth0 down to take the network interface offline, because it validates both failover as well as fencing. On the active host. Manual intervention for dual failures was part of the system design, as the safest method to ensure data integrity. Sun Cluster software attempts to.
