# 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.
