# 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 # # 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 # # Basics commands supported are: # raw - Will dd /proc/vmcore into . # # net - Will mount fs and copy /proc/vmcore to # /var/crash/%HOST-%DATE/, supports DNS. # # net - Will scp /proc/vmcore to # :/var/crash/%HOST-%DATE/, supports DNS # NOTE: make sure user has necessary write # permissions on server # # - Will mount -t /mnt and copy # /proc/vmcore to /mnt/var/crash/%DATE/. # NOTE: can be a device node, label or uuid. # # 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 # This directive allows you to use the dump filtering # 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. # # link_delay # Some network cards take a long time to initialize, and # some spanning tree enabled networks do not transmit # user traffic for long periods after a link state # changes. This optional parameter defines a wait # period after a link is activated in which the # initramfs will wait before attempting to transmit # user data. # default # Action to preform instead of mounting root fs and # running init process # reboot: If the default action is reboot simply reboot # the system and loose the core that you are # trying to retrieve. # shell: If the default action is shell, then drop to # an msh session inside the initramfs from # where you can try to record the core manually. # Exiting this shell reboots the system. # NOTE: If no default action is specified, the initramfs # will mount the root file system and run init. #raw /dev/sda5 #ext3 /dev/sda3 #ext3 LABEL=/boot #ext3 UUID=03138356-5e61-4ab3-b58e-27507ac41937 #net my.server.com:/export/tmp #net user@my.server.com #path /var/crash #core_collector makedumpfile -c #link_delay 60 #default shell
