<resource-agent name="fence_kdump" shortdesc="fencing agent for use with kdump crash recovery service">
<longdesc>fence_kdump is an I/O fencing agent to be used with the kdump
crash recovery service. When the fence_kdump agent is invoked,
it will listen for a message from the failed node that acknowledges
that the failed node it executing the kdump crash kernel.
Note that fence_kdump is not a replacement for traditional
fencing methods. The fence_kdump agent can only detect that a
node has entered the kdump crash recovery service. This allows the
kdump crash recovery service complete without being preempted by
traditional power fencing methods.
Note: the "off" action listen for message from failed node that
acknowledges node has entered kdump crash recovery service. If a valid
message is received from the failed node, the node is considered to be
fenced and the agent returns success. Failure to receive a valid
message from the failed node in the given timeout period results in
fencing failure.</longdesc>
