# Kernel Version string for the -kdump kernel, such as 2.6.13-1544.FC5kdump # If no version is specified, then the init script will try to find a # kdump kernel with the same version number as the running kernel. KDUMP_KERNELVER="" # The kdump commandline is the command line that needs to be passed off to # the kdump kernel. This will likely match the contents of the grub kernel # line. For example: # KDUMP_COMMANDLINE="ro root=LABEL=/" # Dracut depends on proper root= options, so please make sure that appropriate # root= options are copied from /proc/cmdline. In general it is best to append # command line options using "KDUMP_COMMANDLINE_APPEND=". # If a command line is not specified, the default will be taken from # /proc/cmdline KDUMP_COMMANDLINE="" # This variable lets us remove arguments from the current kdump commandline # as taken from either KDUMP_COMMANDLINE above, or from /proc/cmdline # NOTE: some arguments such as crashkernel will always be removed KDUMP_COMMANDLINE_REMOVE="hugepages hugepagesz slub_debug quiet log_buf_len swiotlb cma hugetlb_cma ignition.firstboot" # This variable lets us append arguments to the current kdump commandline # after processed by KDUMP_COMMANDLINE_REMOVE KDUMP_COMMANDLINE_APPEND="irqpoll nr_cpus=1 reset_devices novmcoredd cma=0 hugetlb_cma=0" # Any additional kexec arguments required. In most situations, this should # be left empty # # Example: # KEXEC_ARGS="--elf32-core-headers" KEXEC_ARGS="" #Where to find the boot image #KDUMP_BOOTDIR="/boot" #What is the image type used for kdump KDUMP_IMG="vmlinuz" # Logging is controlled by following variables in the first kernel: # - @var KDUMP_STDLOGLVL - logging level to standard error (console output) # - @var KDUMP_SYSLOGLVL - logging level to syslog (by logger command) # - @var KDUMP_KMSGLOGLVL - logging level to /dev/kmsg (only for boot-time) # # In the second kernel, kdump will use the rd.kdumploglvl option to set the # log level in the above KDUMP_COMMANDLINE_APPEND. # - @var rd.kdumploglvl - logging level to syslog (by logger command) # - for example: add the rd.kdumploglvl=3 option to KDUMP_COMMANDLINE_APPEND # # Logging levels: no logging(0), error(1),warn(2),info(3),debug(4) # # KDUMP_STDLOGLVL=3 # KDUMP_SYSLOGLVL=0 # KDUMP_KMSGLOGLVL=0
