# kdump-tools configuration # --------------------------------------------------------------------------- # USE_KDUMP - controls kdump will be configured # 0 - kdump kernel will not be loaded # 1 - kdump kernel will be loaded and kdump is configured # KDUMP_SYSCTL - controls when a panic occurs, using the sysctl # interface. The contents of this variable should be the # "variable=value ..." portion of the 'sysctl -w ' command. # If not set, the default value "kernel.panic_on_oops=1" will # be used. Disable this feature by setting KDUMP_SYSCTL=" " # Example - also panic on oom: # KDUMP_SYSCTL="kernel.panic_on_oops=1 vm.panic_on_oom=1" # USE_KDUMP=1 #KDUMP_SYSCTL="kernel.panic_on_oops=1" # --------------------------------------------------------------------------- # Kdump Kernel: # KDUMP_KERNEL - A full pathname to a kdump kernel. # KDUMP_INITRD - A full pathname to the kdump initrd (if used). # If these are not set, kdump-config will try to use the current kernel # and initrd if it is relocatable. Otherwise, you will need to specify # these manually. #KDUMP_KERNEL= #KDUMP_INITRD= # --------------------------------------------------------------------------- # vmcore Handling: # KDUMP_COREDIR - local path to save the vmcore to. # KDUMP_FAIL_CMD - This variable can be used to cause a reboot or # start a shell if saving the vmcore fails. If not set, "reboot -f" # is the default. # Example - start a shell if the vmcore copy fails: # KDUMP_FAIL_CMD="echo 'makedumpfile FAILED.'; /bin/bash; reboot -f" KDUMP_COREDIR="/mnt" #KDUMP_FAIL_CMD="reboot -f" # --------------------------------------------------------------------------- # Makedumpfile options: # MAKEDUMP_ARGS - extra arguments passed to makedumpfile (8). The default, # if unset, is to pass '-c -d 31' telling makedumpfile to use compression # and reduce the corefile to in-use kernel pages only. #MAKEDUMP_ARGS="-c -d 31" # --------------------------------------------------------------------------- # Kexec/Kdump args # KDUMP_KEXEC_ARGS - Additional arguments to the kexec command used to load # the kdump kernel # Example - Use this option on x86 systems with PAE and more than # 4 gig of memory: # KDUMP_KEXEC_ARGS="--elf64-core-headers" # KDUMP_CMDLINE - The default is to use the contents of /proc/cmdline. # Set this variable to override /proc/cmdline. # KDUMP_CMDLINE_APPEND - Additional arguments to append to the command line # for the kdump kernel. If unset, it defaults to "irqpoll maxcpus=1 nousb" #KDUMP_KEXEC_ARGS="" #KDUMP_CMDLINE="" #KDUMP_CMDLINE_APPEND="irqpoll maxcpus=1 nousb" # --------------------------------------------------------------------------- # Architecture specific Overrides:
