Re: [HPDD-discuss] Lustre Client 2.4.1 on Ubuntu Precise 12.04 with Mellanox OFED gen2

Hi Patrice, Patrice> Hi, Patrice> Somebody has ever successfully compiled Lustre Client Patrice> 2.4.1 on Ubuntu Patrice> Precise 12.04 with Mellanox OFED 2.0.3? we have built (and support) it (server + client) under Ubuntu 12.04.x for Qlustar. However, we use kernel 2.6.32.x for the server and kernel 3.12.x (in-kernel client with some fixes see Lustre jira) for the client and build against the stock OFED sources (for 2.6.32.x). I'm not sure whether the stock 12.04 kernels (3.2 or higher) will support a 2.4.1 compile without major modifications (a client only compile obviously has a lot better chances though).

For stock OFED I have: Documentation/ configure.mk.kernel kernel-build/ makefile@ patches/ Makefile@ drivers/ kernel_addons/ net/ config.mk include/ kernel_patches/ ofa_kernel.spec@ configure@ kernel/ lib/ ofed_scripts/ Does Mellanox OFED have the same layout? If not, it's possible the headers can't be found. Patrice> I tried a couple of patches/hacks found on Google but Patrice> without success. Patrice> Thanks. Good luck, Roland -- https://qlustar.com
