I/O stall with SuSE 10 Kernel [message #10572]

Hello

I have setup a OpenVZ Server for the development with the SuSE 10
Kerenl found at http://openvz.org/download/kernel/suse10/
Teh machine has been running fine until this morning. It first get
insane slow and then simply stops doing any file IO at all. It was not
loaded by any means before and i can found no error messages in the
logfiles. The only way to get the maschine up again was by
power-cycling. The Hardware we are using runs fine on other heavily
loaded SuSE 10 machines :

- Tyan Thunder K8SD Pro with 2xOpteron 248 and 4GB ECC RAM
- ICP Vortex GDT6513RS RAID Controller

No additional PCI cards.

Can anyone give a hint where this problem might come from?

Thanxs

Andreas

Well, in such situations it usually makes sense to check vmstat,
free memory (you can simply load vzwdog module).

But I would recommend you to upgrade to 2.6.18-028test015 kernel.
It has some new features and is our main target as the stable kernel
with long life support.

Thanks,
Kirill

I had "top" running at the time the machine was freezing, but there was
plenty of RAM (~ 2GB) still free.

Is there a SuSE kompatibel rpm or do i have to compile the kernel
myself? It is vital to me that the ICP Controller is supported and i
don't know if the Fedora kernels do.

You can install OpenVZ kernel from rpm using --nodeps option. It should
work properly! If it doesn't - it is a bug. The second way is to compile
kernel yourself.
If your controller is supported by SuSE kernel then with a great chance
it is supported by our kernel. If it isn't supported - file a bug to
OpenVZ and we probably include support of your device. If you want to
know more precisely is your controller supported or note, send us
output of `lspci` and `lspci -n` commands and we inform you.

Hallo

Thanxs for your help. If have included the lspci (-n) and would be glad
to here that the device is supported by the latest (standard FC5?)
kernel from openvz. It is smaller in size than the SuSE openvz kernel
so i was afraid that there are missing some SuSE centric drivers.

Regards

Andreas

Hello again,

I'm glad to inform you that both 2.6.18-028test and 2.6.9-023stable
series of OpenVZ kernels support your device.
Also I'd like to say, that OpenVZ kernels are more closely bind to RHEL
kernels, not to FC ones. For example, 2.6.9-023stable series is based on
RHEL4 kernel.
