Hello folks:
First of all, may I congratulate you on creating a great distribution. One of the reasons I chose SL is because I had heard great things about the user community. I’m hoping to get your help on an issue that I’m facing.
I’ve been running SL for a couple of weeks now on a server that we assembled. I’ve been seeing kernel panics after I try to run bonnie++ (a hdd benchmarking utility). To debug this issue, I need to collect the kdump files so that I can examine them using crash.
When I induce a kernel panic with `echo c > /proc/sysrq-trigger` and I look at the /var/crash location, I don’t see any dump files created.
I’ve tried everything, read the upstream documents and followed them very closely. I don’t know what I’m doing wrong. The following are the contents of my /etc/kdump.conf file:
debug_mem_level 2
debug_mem_level 2
path /var/crash
ext4 /dev/mapper/vg_bayes-lv_root
core_collector makedumpfile -d 17 –c
Has anyone seen a similar issue with kdump? Once, I am able to get the kernel dump, then I will bother you folks again for help in trying to understanding what is causing the kernel panics. I’m using a SuperMicro H8QGI-F motherboard.
Regards,
Abhikesh
