# 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 -c --message-level 1 -d 31".

#			  Default core_collector for other targets is:

#			  "makedumpfile -c --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.
