You should download from the Whamcloud download site, for a start:
Typically, the Lustre server does nothing but run Lustre. For that reason
there is generally little risk
from using our current version on the server platforms. If your clients
require a particular kernel version, you
would have to build lustre-client and lustre-client modules only.

I would reccomend
as a useful resource.
