OpenVZ and Lustre [message #29107]

Hi all,

I would like to know whether someone has ever succeeded in using an OpenVZ node as a Lustre Client.

I use a 2.6.18 vanilla based Kernel which I patched in order to have openVZ support.
The creation of the modules for Lustre works but when I try to load them I have got numerous errors.

I hope someone could help me!

If you are looking for an intelligent response, you will need to be a bit more specific then this.

you need to download the kernel source, and compile the kernel and those modules on the same system.

Ok rickb but that's what I did Confused

I first installed the kernel-smp-2.6.18-ovz028stab053.5.i686.rpm kernel on the node. Then I reboot on this kernel.

I download the vanilla source code 2.6.18 (kernel.org) then I applied the openvz patch : patch-ovz028stab053.5-combined.gz

And I finally use Lustre source code (1.6.4.3) to make the rpms for the client (patchless method)

Am I wrong doing that?

Let me know how you make out with this. I tried GFS and it didn't work the way I wanted, and the OpenVZ team suggested staying away from NFS. I am trying to provide an environment where I can fail a VE over to another piece of hardware, preferably using a shared drive among three or more machines.

I'd be interested in knowing your config and how you make out.

Please let me know.
