# - Will dd /proc/vmcore into .
# Use persistent device names for partition devices,
# such as /dev/vg/.
#
# nfs
# - Will mount nfs to , and copy /proc/vmcore to
# //%HOST-%DATE/, supports DNS.
#
# ssh
# - Will scp /proc/vmcore to :/%HOST-%DATE/,
# supports DNS.
# NOTE: make sure the user has write permissions on the server.
#
# sshkey
# - Will use the sshkey to do ssh dump.
# Specify the path of the ssh key to use when dumping
# via ssh. The default value is /root/.ssh/kdump_id_rsa.
#
#
# - Will mount -t , and copy
# /proc/vmcore to //%HOST_IP-%DATE/.
# NOTE: can be a device node, label or uuid.
# It's recommended to use persistent device names
# such as /dev/vg/.
# Otherwise it's suggested to use label or uuid.
#
# path
# - "path" represents the file system path in which vmcore
# will be saved. If a dump target is specified in
# kdump.conf, then "path" is relative to the specified
# dump target.
#
# Interpretation of "path" changes a bit if the user didn't
# specify any dump target explicitly in kdump.conf. In this
# case, "path" represents the absolute path from root. The
# dump target and adjusted path are arrived at automatically
# depending on what's mounted in the current system.
#
# Ignored for raw device dumps. If unset, will use the default
# "/var/crash".
#
# core_collector
# - This allows you to specify the command to copy
# the vmcore. The default is makedumpfile, which on
# some architectures can drastically reduce vmcore 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.
# The default core_collector for raw/ssh dump is:
# "makedumpfile -F -l --message-level 1 -d 31".
# The default core_collector for other targets is:
# "makedumpfile -l --message-level 1 -d 31".
#
# "makedumpfile -F" will create a flattened vmcore.
# You need to use "makedumpfile -R" to rearrange the dump data to
# a normal dumpfile readable with analysis tools. For example:
# "makedumpfile -R vmcore < vmcore.flat".
#
# For core_collector format details, you can refer to
# kexec-kdump-howto.txt or kdump.conf manpage.
#
# kdump_post
# - This directive allows you to run a executable binary
# or script after the vmcore dump process terminates.
# The exit status of the current dump process is fed to
# the executable binary or script as its first argument.
#
# kdump_pre
# - Works like the "kdump_post" directive, but instead of running
# after the dump process, runs immediately before it.
# Exit status of this binary is interpreted as follows:
# 0 - continue with dump process as usual
# non 0 - reboot the system
#
# extra_bins
# - This directive allows you to specify additional binaries or
# shell scripts to be included in the kdump initrd.
# Generally they are useful in conjunction with a kdump_post
# or kdump_pre binary or script which depends on these extra_bins.
#
# extra_modules
# - This directive allows you to specify extra kernel modules
# that you want to be loaded in the kdump initrd.
# Multiple modules can be listed, separated by spaces, and any
# dependent modules will automatically be included.
#
# default
# - Action to perform in case dumping fails.
# reboot: Reboot the system.
# halt: Halt the system.
# poweroff: Power down the system.
# shell: Drop to a bash shell.
# Exiting the shell reboots the system.
# dump_to_rootfs: Dump vmcore to rootfs from initramfs context and
# reboot. Useful when non-root dump target is specified.
# The default option is "reboot".
#
# force_rebuild <0 | 1>
# - By default, kdump initrd will only be rebuilt when necessary.
# Specify 1 to force rebuilding kdump initrd every time when kdump
# service starts.
#
# force_no_rebuild <0 | 1>
# - By default, kdump initrd will be rebuilt when necessary.
# Specify 1 to bypass rebuilding of kdump initrd.
#
# force_no_rebuild and force_rebuild options are mutually
# exclusive and they should not be set to 1 simultaneously.
#
# override_resettable <0 | 1>
# - Usually an unresettable block device can't be a dump target.
# Specifying 1 when you want to dump even though the block
# target is unresettable
# By default, it is 0, which will not try dumping destined to fail.
#
# dracut_args
# - Pass extra dracut options when rebuilding kdump initrd.
#
# fence_kdump_args
# - Command line arguments for fence_kdump_send (it can contain
# all valid arguments except hosts to send notification to).
#
# fence_kdump_nodes
# - List of cluster node(s) except localhost, separated by spaces,
# to send fence_kdump notifications to.
# (this option is mandatory to enable fence_kdump).
