fence_kdump_send - send kdump acknowlegement message to cluster nodes
is a utility used to send messages that acknowledge that
the node has entered the kdump crash recovery service. This utility is
intended to be used the the fence_kdump
agent as a means detect that a
failed node has entered the kdump crash recovery service. The
utility is typically run from within the kdump kernel
after a cluster node has encountered a kernel panic. Once the cluster node has
entered the kdump crash recovery service, fence_kdump_send
periodically send messages to all cluster nodes. When the fence_kdump
agent receives a valid message from the failed node, fencing is complete.
