Please also note that if you are using at RedHat System, that you should use a patch Lustre Server version on the NFS export node (lustre client), as the RedHat default 4K stacksize is too small and Lustre patched kernels have increased that to 8K (default on all system except RHEL). Cheers, Bernd PS: Btw, Ciemat has a DDN Lustre system, so you could also send requests to support at ddn.com (please add [Lustre] in the subject line). -- Bernd Schubert DataDirect Networks
Yes, I''am using a RedHat system (centos 5.2). Please, colud you say me, where I can found that patch Lustre Sever?

Do *NOT* use 1.8.0 please, that is really old. You can easily install an updated kernel and Lustre version on centos 5.2. So you may install upstream Oracle 1.8.4 (downloads.lustre.org). We also have patched 1.8.3-ddn3.3 with latest RedHat security patches (and patches for Lustre): http://eu.ddn.com:8080/lustre/lustre/1.8.3/ddn3.3/ (1.8.4-ddnX is in testing).
