Kexec/Kdump: Managing Linux Crash Dumps
For a long time, Linux did not have a standard mechanism for capturing
crash dumps. Different distributions included different techniques.
In the 2.6 kernels we finally have a common method for managing crash
dumps using kexec and kdump. This talk will describe the technologies
involved and how to configure and manage a production environment to
Kdump is a new kernel crash dumping mechanism and is very reliable
because crash dump is captured from the context of a freshly booted
kernel and not from the context of the crashed kernel. Kdump uses
kexec to boot into a second kernel whenever the system crashes. This
second kernel, often called the capture kernel, boots with very little
memory and captures the dump image. The first kernel reserves a
section of memory that the second kernel uses to boot. Kexec enables
booting the capture kernel without going through the BIOS hence
contents of first kernel's memory are preserved, which is essentially
the kernel crash dump.
