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
              Print version and exit.

       -h, --help
              Print usage and exit.

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
              Print XML metadata to standard output.
