# 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 default action which can be configured via # the "default" 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 scp /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>/%HOST_IP-%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 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 <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. # # 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 - reboot the system # # 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. # # default <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. # 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 <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). # #raw /dev/vg/lv_kdump #ext4 /dev/vg/lv_kdump #ext4 LABEL=/boot #ext4 UUID=03138356-5e61-4ab3-b58e-27507ac41937 #nfs my.server.com:/export/tmp #ssh user@my.server.com #sshkey /root/.ssh/kdump_id_rsa path /var/crash core_collector makedumpfile -l --message-level 1 -d 31 #core_collector scp #kdump_post /var/crash/scripts/kdump-post.sh #kdump_pre /var/crash/scripts/kdump-pre.sh #extra_bins /usr/bin/lftp #extra_modules gfs2 #default shell #force_rebuild 1 #force_no_rebuild 1 #dracut_args --omit-drivers "cfg80211 snd" --add-drivers "ext2 ext3" #fence_kdump_args -p 7410 -f auto -c 0 -i 10 #fence_kdump_nodes node1 node2
