13.2.2 Files Used by Kdump

The Kernel Dump Configuration GUI modifies the following files:




Appends the crashkernel option to the kernel line to specify the amount of reserved memory and any offset value.


Sets the location where the dump file can be written, the filtering level for the makedumpfile command, and the default behavior to take if the dump fails. See the comments in the file for information about the supported parameters.

If you edit these files, you must reboot the system to have the changes take effect.
