NAME

       fence_kdump - fencing agent for use with kdump crash recovery service

SYNOPSIS

       fence_kdump [OPTIONS]...

DESCRIPTION

       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.

OPTIONS

       -n, --nodename=NODE
	      Name or IP address of node to be fenced. This option is required for the "off" action. (default: none)

       -p, --ipport=PORT
	      IP port number that the fence_kdump agent will use to listen for messages. (default: 7410)

       -f, --family=FAMILY
	      IP network family. Force the fence_kdump agent to use a specific family. The value for FAMILY can  be  "auto",  "ipv4",  or  "ipv6".
	      (default: auto)

       -o, --action=ACTION
	      Fencing action to perform. The value for ACTION can be either "off" or "metadata". (default: off)

       -t, --timeout=TIMEOUT
	      Numer  of  seconds  to  wait  for  message from failed node. If no message is received within TIMEOUT seconds, the fence_kdump agent
	      returns failure. (default: 60)

       -v, --verbose
	      Print verbose output.

       -V, --version

STDIN PARAMETERS

       These parameters are passed to fence_kdump via standard input if no command-line options are present.

       nodename=NODE
	      Name or IP address of node to be fenced. This option is required for the "off" action. (default: none)

       ipport=PORT
	      IP port number that the fence_kdump agent will use to listen for messages. (default: 7410)

       action=ACTION
	      Fencing action to perform. The value for ACTION can be either "off" or "metadata". (default: off)

       timeout=TIMEOUT
	      Numer of seconds to wait for message from failed node. If no message is received	within	TIMEOUT  seconds,  the	fence_kdump  agent
	      returns failure. (default: 60)

ACTIONS

       off    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.

       metadata
