# 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 a time. If dump

# to configured dump target fails, the default action will be preformed.

# Default action may be configured with the "default" directive below.

#

# Basics commands supported are:

# 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 /usr/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.

#			  For ssh dump, scp should be used instead of cp.

#

# raw <partition>	- Will write /proc/vmcore into raw <partition>.

#

# nfs <nfs mount>	- Will mount fs and copy /proc/vmcore to

#			  <mnt>/<path>/%HOST-%DATE/, supports DNS.

#

# nfs4 <nfs mount>      - Will use NFSv4 instead of NFSv3

#

# net <nfs mount>       - This is a deprecated option to transfer vmcore over

#			  nfs.  Use "nfs" option instead.

#

# ssh <user@server>	- Will copy /proc/vmcore to

#			  <user@server>:<path>/%HOST-%DATE/ via SSH,

#			  supports DNS. If makedumpfile is the core_collector,

#			  it is piped to an "ssh" shell, otherwise use the

#			  specified core_collector like scp.

#			  NOTE: make sure user has necessary write

#			  permissions on server

#

# net <user@server>     - This is a deprecated option to transfer vmcore over

#			  ssh.  Use "ssh" option instead.

#

# <fs type> <partition> - Will mount -t <fs type> <partition> /mnt and copy

#		 	  /proc/vmcore to /mnt/<path>/127.0.0.1-%DATE/.

#			  NOTE: <partition> can be a device node, label or uuid.

#

# disk_timeout <seconds>

#			- Number of seconds to wait for disks to appear prior

#			  to continue to save dump. By default kdump waits

#			  180 seconds for the disks to show up it needs. This

#			  can be useful in some cases if disk never shows up

#			  (Either because disk was removed or because kdump is

#			  waiting on wrong disk).

#

# link_delay <seconds>

#			- Some network cards take a long time to initialize, and

#			  some spanning tree enabled networks do not transmit

#			  user traffic for long periods after a link state

#			  changes.  This optional parameter defines a wait

#			  period after a link is activated in which the

#			  initramfs will wait before attempting to transmit

#			  user data.

#

# 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/halt 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.

# 			  Module name should be specified without ".ko" suffix.

#

# options <module> <option list>

#			- This directive allows you to specify options to apply

#			  to modules in the initramfs.  This directive overrides

#			  options specified in /etc/modprobe.conf. Module name

#			  should be specified without ".ko" suffix.

#

# blacklist <module|directory>

#			- Prevents modules from being loaded in the initframfs,

#			  either directly during auto-created insmod calls or as

#			  a dependency of another module load. A specific module

#			  or a directory can be specified. In the latter case,

#			  all modules found below the specified directory will

#			  be excluded. This directive can be specified multiple

#			  times or as a space separated list. Module name should

#			  be specified without ".ko" suffix.

#

# sshkey <path>

#			- Specifies the path of the ssh identity file you want

#			  to use when doing ssh dump. It must be a private key,

#			  the default value is /root/.ssh/kdump_id_rsa. When

#			  progagating public key, the key is assumed to be

#			  identity_file.pub which by default is

#			  /root/.ssh/kdump_id_rsa.pub.

#

# default <reboot | halt | poweroff | shell | mount_root_run_init>

#			- 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 hush session inside the initramfs from

#				  where you can try to record the core manually.

#				  Exiting this shell reboots the system.

#	     mount_root_run_init: Mount root filesystem and run init. Kdump

#			  	    initscript will try to save dump to root

#			  	    filesystem in /var/crash dir. This will

#			  	    likely require a lot more memory to

#			  	    be reserved for kdump kernel.

#

# debug_mem_level <0-3>

#                       - Turns on debug/verbose output of kdump scripts

#                         regarding free/used memory at various points of

#                         execution. Higher level means more debugging output.

#                         0 - no output

#                         1 - partial /proc/meminfo

#                         2 - /proc/meminfo

#                         3 - /proc/meminfo + /proc/slabinfo

#

# force_rebuild <0 | 1>

#			- By default, kdump initrd only will be rebuilt when

#			  necessary. Specify 1 here to force rebuilding kdump

#			  initrd every time when kdump service starts.

#

# fence_kdump_args <arg(s)>

#			- Command line arguments for fence_kdump_send (it can contain

#			all valid arguments except hosts to send notification to).

#

# fence_kdump_nodes <node(s)>

# 			- List of cluster node(s) separated by space to send fence_kdump

# 			notification to (this option is mandatory to enable fence_kdump).
