Thank Leon, but that is just the debuginfo. I have been looking at http://linuxsysconfig.com/2013/03/kdump-on-centos-6/

and it shows use yum --enablerepo=debug install kexec-tools crash kernel-debug kernel-debuginfo-`uname -r`

but when I run that command I get:

# yum --enablerepo=debug install kexec-tools crash kernel-debug kernel-debuginfo-`uname -r` Setting up Install Process Package kexec-tools-2.0.0-273.el6.x86_64 already installed and latest version Package crash-6.1.0-5.el6.x86_64 already installed and latest version Package kernel-debuginfo-2.6.32-358.23.2.el6.centos.plus.x86_64 already installed and latest version Resolving Dependencies --> Running transaction check ---> Package kernel-debug.x86_64 0:2.6.32-431.11.2.el6 will be installed --> Processing Dependency: kernel-firmware >= 2.6.32-431.11.2.el6 for package: kernel-debug-2.6.32-431.11.2.el6.x86_64 --> Running transaction check ---> Package kernel-firmware.noarch 0:2.6.32-358.23.2.el6.centos.plus will be updated ---> Package kernel-firmware.noarch 0:2.6.32-431.11.2.el6 will be an update --> Finished Dependency Resolution

I am running kernel 2.6.32-358.23.2.el6.centos.plus.x86_64 and I would like the matching kernel-debug rpm not kernel-debug.x86_64 0:2.6.32-431.11.2.el6

The kernel-debug package has never been built for the centosplus kernel as far as I know. It requires its own config file. I suggest you use the distro kernel if you need to debug something. Do you have a particular reason why you want to do this with the plus kernel?

Hi Akemi,

We have a remote unit that has been crashing and I wanted to collect the dump. We can't use the latest kernel because it breaks multicasting with gres. We use OSPF over multiple gre tunnels and the .358 kernel is the latest one that works correctly.

I have tested the crash setup and it seems to work ok without having the kernel-dump rpm installed so it doesn't seem to be absolutely necessary. Maybe only if you have a limited amount of memory.

Regards,
