# Configures where to put the kdump /proc/vmcore files
#
# This file contains a series of commands to perform (in order) when a
# kernel crash has happened and the kdump kernel has been loaded.  Directives in
# this file are only applicable to the kdump initramfs, and have no effect if
# the root filesystem is mounted and the normal init scripts are processed
#
# Currently only one dump target and path may be configured at once
# if the configured dump target fails, the default action will be preformed
# the default action may be configured with the default directive below.  If the
# configured dump target succedes 
#
# Basics commands supported are:
# raw <partition>	- Will dd /proc/vmcore into <partition>.
#			  Use persistent device names for partition devices,
#			  such as /dev/vg/<devname>.
#
# nfs <nfs mount>	- Will mount fs and copy /proc/vmcore to
#			  <mnt>/var/crash/%HOST-%DATE/, supports DNS.
#
# ssh <user@server>	- Will scp /proc/vmcore to
#			  <user@server>:/var/crash/%HOST-%DATE/, supports DNS
#			  NOTE: make sure user has necessary write
#			  permissions on server
#
# sshkey <path>		- Will use the sshkey to do ssh dump
#			  Specifies the path of the ssh key you want to use
#			  when do ssh dump, the default value is
#			  /root/.ssh/kdump_id_rsa.
#
# <fs type> <partition> - Will mount -t <fs type> <partition> /mnt and copy
#		 	  /proc/vmcore to /mnt/var/crash/%DATE/.
#			  NOTE: <partition> can be a device node, label or uuid.
#			  It's recommended to use persistent device names
#			  such as /dev/vg/<devname>.
#			  Otherwise it's suggested to use label or uuid.
#
# path <path> 		- Append path to the filesystem device which you are
#			  dumping to.  Ignored for raw device dumps.
#		 	  If unset, will default to /var/crash.
#
# core_collector <command> <options>
#			- This allows you to specify the command to copy
#			  the vmcore.  You could use the dump filtering
#			  program makedumpfile, the default one, to retrieve
#			  your core, which on some arches can drastically
#			  reduce core file size. See /sbin/makedumpfile --help
#			  for a list of options. Note that the -i and -g
#			  options are not needed here, as the initrd will
#			  automatically be populated with a config file
#			  appropriate for the running kernel.
#			  Default core_collector for raw/ssh dump is:
#			  "makedumpfile -F -l --message-level 1 -d 31".
#			  Default core_collector for other targets is:
#			  "makedumpfile -l --message-level 1 -d 31".
#			  For core_collector format details please refer to
#			  kexec-kdump-howto.txt or kdump.conf manpage.
#
# kdump_post <binary | script>
# 			- This directive allows you to run a specified
# 			  executable just after the memory dump process
# 			  terminates. The exit status from the dump process
# 			  is fed to the kdump_post executable, which can be
# 			  used to trigger different actions for success or
# 			  failure.
#
# kdump_pre <binary | script>
#			- works just like the kdump_post directive, but instead
#			  of running after the dump process, runs immediately
#			  before.  Exit status of this binary is interpreted
#			  as follows:
#			  0 - continue with dump process as usual
#			  non 0 - reboot the system
#
# extra_bins <binaries | shell scripts>
# 			- This directive allows you to specify additional
# 			  binaries or shell scripts you'd like to include in
# 			  your kdump initrd. Generally only useful in
# 			  conjunction with a kdump_post binary or script that
# 			  relies on other binaries or scripts.
#
# extra_modules <module(s)>
# 			- This directive allows you to specify extra kernel
# 			  modules that you want to be loaded in the kdump
# 			  initrd, typically used to set up access to
# 			  non-boot-path dump targets that might otherwise
# 			  not be accessible in the kdump environment. Multiple
# 			  modules can be listed, separated by a space, and any
# 			  dependent modules will automatically be included.
#
# default <reboot | halt | poweroff | shell | dump_to_rootfs>
#			- Action to preform in case dumping to intended target
#			  fails. If no default action is specified, "reboot" 
#			  is assumed default.
#			  reboot: If the default action is reboot simply reboot
#				  the system and loose the core that you are
#				  trying to retrieve.
#			  halt:   If the default action is halt, then simply
#				  halt the system after attempting to capture
#				  a vmcore, regardless of success or failure.
#			  poweroff: The system will be powered down
#			  shell:  If the default action is shell, then drop to
#				  an shell session inside the initramfs from
#				  where you can try to record the core manually.
#				  Exiting this shell reboots the system.
#				  Note: kdump uses bash as the default shell.
#			  dump_to_rootfs: If non-root dump target is specified,
#				  the default action can be set as dump_to_rootfs.
#				  That means when dump to target fails, dump vmcore
#				  to rootfs from initramfs context and reboot. 
#
# force_rebuild <0 | 1>
#			- By default, kdump initrd only will be rebuilt when
#			  necessary. Specify 1 to force rebuilding kdump
#			  initrd every time when kdump service starts.
#
#override_resettable <0 | 1>
#			- Usually a unresettable block device can't be dump target.
#			Specifying 1 means though block target is unresettable, user
#			understand this situation and want to try dumping. By default,
#			it's set to 0, means not to try a destined failure.
#
# dracut_args <arg(s)>
#			- Pass extra dracut options when rebuilding kdump
#			  initrd.
