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.
