# Configures where to put the kdump /proc/vmcore files
#
# This file contains a series of commands to perform (in order) when a
2008-06-05 15:18:53 +00:00
# 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
2008-06-05 15:18:53 +00:00
# the default action may be configured with the default directive below. If the
# configured dump target succedes

#
# Basics commands supported are:
2006-12-15 21:05:01 +00:00
# raw <partition> - Will dd /proc/vmcore into <partition>.
#
# net <nfs mount> - Will mount fs and copy /proc/vmcore to
# <mnt>/var/crash/%HOST-%DATE/, supports DNS.
#
# net <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.
#
2006-12-15 21:05:01 +00:00
# <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.
#
# 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 makedumpfile <options>
2008-06-05 15:18:53 +00:00
# - This directive allows you to use the dump filtering
2006-12-15 21:05:01 +00:00
# program makedumpfile 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.
#
2008-06-05 15:18:53 +00:00
# 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.
2008-06-05 15:18:53 +00:00
#
# 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>
# - Action to preform in case dumping to intended target
# fails. If no default action is specified saving vmcore
# to root fs is assumed default.
2006-12-15 21:05:01 +00:00
# reboot: If the default action is reboot simply reboot
# the system and loose the core that you are
# trying to retrieve.
2008-06-05 15:18:53 +00:00
# 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
2006-12-15 21:05:01 +00:00
# shell: If the default action is shell, then drop to
# an shell session inside the initramfs from
2006-12-15 21:05:01 +00:00
# where you can try to record the core manually.
# Exiting this shell reboots the system.
# Note: kdump uses bash as the default shell.
