OpenVZ and Lustre
type: item
description: 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!

description: Ok rickb but that's what I did 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?

description: 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. sean
