Producing Lustre server patches is a considerable effort, so it is only done on a limited number of vendor kernels.  Currently we provide server patches for RHEL5 on 1.8.x/2.1.x and RHEL6 on 2.1.x and later.  There are also patches for SLES11 in the Git repo.  Sorry, we don't have server patches for Ubuntu.

It may be possible to install the RHEL kernel RPM on your Ubuntu system using "alien", but I have no idea if that works.  Alternately, you could try getting the RHEL kernel sources and compiling it using "make deb".  Again, no idea if this works.

Far better is to just install RHEL/Centos onto your Lustre servers and use Ubuntu on the clients.

Cheers, Andreas
