# This file contains a series of commands to perform (in order) in the kdump

# kernel after a kernel crash in the crash kernel(1st kernel) has happened.

#

# Directives in this file are only applicable to the kdump initramfs, and have

# no effect once the root filesystem is mounted and the normal init scripts are

# processed.

#

# Currently, only one dump target and path can be specified.  If the dumping to

# the configured target fails, the failure action which can be configured via

# the "failure_action" directive will be performed.

#

# Supported options:

#

# 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 nfs to <mnt>, and copy /proc/vmcore to

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

#

# ssh <user@server>

#           - Will save /proc/vmcore to <user@server>:<path>/%HOST-%DATE/,

#             supports DNS.

#             NOTE: make sure the user has write permissions on the server.

#

# sshkey <path>

#           - 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.

#

# <fs type> <partition>

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

#             /proc/vmcore to <mnt>/<path>/%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>

#           - "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 <command> <options>

#           - 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 7 -d 31".

#             The default core_collector for other targets is:

#             "makedumpfile -l --message-level 7 -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 <binary | script>

#           - 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.

#             All files under /etc/kdump/post.d are collectively sorted

#             and executed in lexical order, before binary or script

#             specified kdump_post parameter is executed.

#

# kdump_pre <binary | script>

#           - 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 - run the final action (reboot/poweroff/halt)

#             All files under /etc/kdump/pre.d are collectively sorted and

#             executed in lexical order, after binary or script specified

#             kdump_pre parameter is executed.

#             Even if the binary or script in /etc/kdump/pre.d directory

#             returns non 0 exit status, the processing is continued.

#

# extra_bins <binaries | shell scripts>

#           - 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 <module(s)>

#           - 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.

#

# failure_action <reboot | halt | poweroff | shell | dump_to_rootfs>

#           - 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 by default,

#                       or perform "final_action".

#             dump_to_rootfs:  Dump vmcore to rootfs from initramfs context and

#                       reboot by default or perform "final_action".

#                       Useful when non-root dump target is specified.

#             The default option is "reboot".

#

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

#           - Same as the "failure_action" directive above, but this directive

#             is obsolete and will be removed in the future.

#

# final_action <reboot | halt | poweroff>

#           - Action to perform in case dumping succeeds. Also performed

#             when "shell" or "dump_to_rootfs" failure action finishes.

#             Each action is same as the "failure_action" directive above.

#             The default 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 <arg(s)>

#           - Pass extra dracut options when rebuilding kdump initrd.

#

# 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) except localhost, separated by spaces,

#             to send fence_kdump notifications to.

#             (this option is mandatory to enable fence_kdump).
