Hello,
If anyone can help me with this I'd appreciate any pointers.
I have an HP Proliant Microserver which I've installed CentOS 6.2 on and am working my way through my RHCSA training using it as the host for various VM guests. The server has been working reliably since January but in the last week has been crashing most days and today it's crashed 2 times in as may hours and I've hit a brick wall trying to identify the root cause. I can't be sure of this but it tends to crash when I've been using the mouse. The mouse locks up and after 10/15 seconds it crashes.
Diagnosis action so far include:
Un-installing the last yum updates
Booting from a previous kernel
I'm getting vmcore files for each crash but have spent a couple hours this morning trying to figure out how to analyse this I'm no further forward. The debug tools aren't on my server and the instructions I've read online
for example don't work
Example:
Code:
# debuginfo-install kernel
.
Checking for new repos for mirrors
Could not find debuginfo for main pkg: kernel-2.6.32-220.4.1.el6.x86_64
Could not find debuginfo for main pkg: kernel-2.6.32-220.4.2.el6.x86_64
Could not find debuginfo for main pkg: kernel-2.6.32-220.7.1.el6.x86_64
Could not find debuginfo for main pkg: kernel-2.6.32-220.el6.x86_64
No debuginfo packages available to install
At this stage the only viable option I have is to rebuild the whole server and all VM guests which will take some time and coming from a UNIX admin background I'd like to diagnose this (as would be the case in a prod environment) rather than give up and take the easy, yet time consuming, option. Unfortunately I've reached the limit of my knowledge and my search online has proved fruitless.
Although I'd like to get the debug stuff working, I do wonder, at my level, if I'll be able to make much sense or implement any solutions from the results.
