NAME

       mkdumprd - creates initial ramdisk images for kdump crash recovery

SYNOPSIS

       mkdumprd [OPTION]

DESCRIPTION

       mkdumprd creates an initial ram file system for use in conjunction with the booting of a kernel within the kdump framework for crash recov-
       ery.  mkdumprds purpose is to create an initial ram filesystem capable of copying the crashed systems vmcore image to a location  specified
       in /etc/kdump.conf

       mkdumprd  interrogates  the  running system to understand what modules need to be loaded in the initramfs (based on configuration retrieved
       from /etc/kdump.conf)

       mkdumprd add a new dracut module 99kdumpbase and use dracut utility to generate the initramfs.

       mkdumprd was not intended for casual use outside of the service initialization script for the kdump utility, and should not  be	run  manu-
       ally.  If you require a custom kdump initramfs image, it is suggested that you use the kdump service infrastructure to create one, and then
       manually unpack, modify and repack the image.

OPTIONS

       All options here are passed to dracut directly, please refer dracut docs
	      for the info.

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).
