.SH DESCRIPTION
|
|
|
e8ba2f5 |
\fBmkdumprd\fR creates an initial ram file system for use in conjunction with
|
|
|
e8ba2f5 |
the booting of a kernel within the kdump framework for crash recovery.
|
|
|
e8ba2f5 |
\fBmkdumprds\fR purpose is to create an initial ram filesystem capable of copying
|
|
|
e8ba2f5 |
the crashed systems vmcore image to a location specified in \fI/etc/kdump.conf
|
|
|
e8ba2f5 |
|
|
|
e8ba2f5 |
\fBmkdumprd\fR interrogates the running system to understand what modules need to
|
|
|
e8ba2f5 |
be loaded in the initramfs (based on configuration retrieved from
|
|
|
e8ba2f5 |
\fI/etc/kdump.conf)\fR
|
|
|

\fBmkdumprd\fR add a new \fBdracut\fR module 99kdumpbase and use \fBdracut\fR

utility to generate the initramfs.

\fBmkdumprd\fR was not intended for casual use outside of the service
|
|
|
e8ba2f5 |
initialization script for the kdump utility, and should not be run manually. If
|
|
|
e8ba2f5 |
you require a custom kdump initramfs image, it is suggested that you use the
|
|
guest |
4baddcf |
kdump service infrastructure to create one, and then manually unpack, modify and
|
|
|
e8ba2f5 |
repack the image.
