NAME

       fence_kdump_send - send kdump acknowlegement message to cluster nodes

SYNOPSIS

       fence_kdump_send [OPTIONS]... [NODE]...

DESCRIPTION

       fence_kdump_send is a utility used to send messages that acknowledge that the node has entered the kdump crash recovery service. This util-
       ity 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  fence_kdump_send  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 will periodically send messages to all cluster nodes. When  the
       fence_kdump agent receives a valid message from the failed node, fencing is complete.

OPTIONS

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

       -f, --family=FAMILY
	      IP network family. Force the fence_kdump_send utility to use a particular network family. Value for FAMILY can be "auto", "ipv4", or
	      "ipv6". (default: auto)

       -c, --count=COUNT
	      Number of messages to send. If COUNT is zero, fence_kdump_send will send messages indefinitely. (default: 0)

       -i, --interval=INTERVAL
	      Time to wait between sending a message. The value for INTERVAL must be greater than zero. (default: 10)

       -v, --verbose
	      Print verbose output.

       -V, --version
	      Print version and exit.

       -h, --help
	      Print usage and exit.

NAME

       mkdumprd - (Re)build the initramfs for kdump

SYNOPSIS

       mkdumprd [-h] [-q] [-f] [-k kernelver] [-i opts]

DESCRIPTION

       mkdumprd (re-)builds the kdump initrd. For kdump, a special initrd is used because

       o   the kdump initrd should include network modules and network configuration (and therefore is larger as the normal initrd used for
           booting),

       o   the kdump initrd should use no splash screen,

       o   the kdump initrd includes kdumptool(8) and all required libraries.

       This script calls mkinitrd(8) with all required parameters. If the initrd already exists, it checks first if the configuration file or the
       kernel are newer, and only rebuilds the initrd if necessary.

OPTIONS

       All option parsing is done via the getopt(3) function, and therefore follows all standard command line parsing rules.

       -h | --help
           Shows help output and exits.

       -k kernelversion
           Specifies the kernel version. If no version is specified and also no kernel or initrd are specified, then mkdumprd uses kdumptool(8) to
           find out the correct kernel and initrd.

       -K kernel
           Specifies the kernel binary. If you specify that option, also specify -I.

       -I initrd
           Specifies the resulting initrd. If you specify that option, also specify -K.

       -q
           Be quiet. Don't output status messages. Used to call mkdumprd(8) from /etc/init.d/kdump init script.

       -i parameters
           Append the specified parameters to mkinitrd(8) call.

FILES

       /etc/sysconfig/kdump
           Kdump configuration. See kdump(5).
