[Lustre-discuss] Lustre, its ldiskfs Module and Debian Lenny
Hi all... I''m working on Lustre in Debian Lenny these days. The major problem is that the packages at sun websites are for RHEL and for the kernel versions lower than 2.6.22 ... The lustre packages exist on debian mirror and I did used the lustre-source README file procedure to build lustre modules. The linux-patch-lustre package contains the patches for 2.6.18 , 2.6.20 and 2.6.22 , while my Lenny kernel verision is 2.6.26 . Any way, I did this dirty work and created a 2.6.26 symlink to apply patch to my kernel... Everything went well and I booted to new kernel and loaded "lnet" and "lustre" kernel modules successfully, but there was NO "ldiskfs" module which the mkfs.lustre utility complains about when creating lustre file systems. So my question is: can one install lustre on new disros like lenny with such new kernels? what''s the solution? I said the main issues; if more infos needed, I''ll write other details. Thank you in advance for any help.

You can''t really use the ext4 in earlier kernels because it is broken. I would suggest to use this kernel instead.

Thank you for reply... So you mean I will have no chance to use Lustre on Debian Lenny with 2.6.26 kernel version? Thanks.

If you do not stick to the 1.8 release for lustre clients you can backport the 1.6.7-2 lustre packages ship with sid. The patchless client works well with the stock kernel of lenny and should be compatible to 1.8 servers. But since I have to build a new Lustre server kernel in the near future and I would prefer to go for the 2.6.27 kernel, which is supported by lustre 1.8.1, I wonder where one can get the source of sles11 kernel, which will be supported officially. Will there be support for vanilla kernel as well? Is there any time estimation for the 1.8.1 release?

You can grab the 1.8.1 pre-release from CVS with the b_release_1_8_1 tag for testing if you like. Cheers, Andreas -- Andreas Dilger Sr. Staff Engineer, Lustre Group Sun Microsystems of Canada, Inc.
