[Users] OpenVZ 2.6.18-ovz028test010.1 crashing on DELL PE 2950

[Jan Tomasek]

Hello,

later I was reporting problems when running 2.6.18-ovz028test005.1 on my
DELL PE 2950. Very similar problem came back with 2.6.18-ovz028test010.1.

HW description:

I'm trying to run OpenVZ on my new DELL PE 2950, it has 8GB of RAM, 2x
Intel Xeon 5160 @ 3.00GHz. 1.1TB FS attached to internal Perc 5/i
adapter and 5.9TB FS from MD1000 attached to Perc 5/E. BIOS and Firmware
of both SAS controlers was updated to latest versions.


After instalation of 2.6.18-ovz028test010.1 I didn't any test, it was
working fine until Thursday morning when masive I/O started. System
stoped completely responding. Screen shows this:

system was not respnding to anything.

After fresh reboot I started simulating masive I/O by

while true; do nice -20 dd if=/dev/zero of=/sklad/`date +"%s"` bs=1G
count=4; done

and in while system started be unresponsive. It does not crashed as
previous, even ping was responding, but that was all. All shells to
system was dead. Alt+SysRq+... printed memory info and cpu registers:

proceces were not respoinding to term/kill signals. I had to reboot system.

I was interested in 2.6.18-ovz028test010.1 because of it's ability log
iptables mesages into VE logs.

Now I'm back running 2.6.18-ovz028test007, it works without any problems.

If I can provide more info please ask me, I will try to help. I learned
how to make that font smaler so more info could fit on screen. I also
can disable that blaking screen which doing something in all crashes I
see with OpenVZ.

Best regards
