We had stability issues with 3.12.x of lustre, we are now using 3.13 (custom built with lustre as module from the kernel source)

Hello all,

Newly subscribed to the list, I've been going through the archives and seen some questions about Lustre client support on recent versions of Debian/Ubuntu distributions.

We have addressed that issue by:
 - building a custom kernel with Lustre client *disabled*, based on Ubuntu's latest available kernel + latest stable patchsets, 3.12.8 for us so far (PS: './debian/rules editconfigs' to disable Lustre)
 - having a separate (easily upgrade-able) 'lustre-dkms' package based on Lustre in-kernel client code + our patches, 3.14rc1~patched for us so far

We use that 3.12.8 kernel + lustre-dkms (3.14rc1~patched) package without any problem on:
 - Ubuntu/Quantal (~100 workstations and computation nodes)
 - Debian/Wheezy with the few libc (>= 2.14) dependencies pulled from Debian/Testing (a few servers requiring Lustre access)
 - (hopefully Ubuntu/Trusty 14.04 in a few weeks)
(against a Lustre 2.6.32/2.4.2 cluster)

I have tarball-ed the required resources at http://www.idiap.ch/~cdufour/download/lustre-dkms.tar.bz2 . It contains the skeleton directory and HOWO.TXT file that should get going those of you who are interested to follow the same path.

Hope it helps.

Best regard,

Cédric
