[Lustre-discuss] Compiling lustre 1.8.1.1 against latest CentOS5 kernel fails.

[Michael Robbert]

I've been following this thread the past few days because I'm in the  
process of trying to upgrade to a fully patched RHEL5 kernel and have  
been having problems getting Lustre modules compiled. Our Lustre  
servers are currently running 1.6.7.2 and I'm hoping to not have to  
upgrade those just yet, but will if we need to. Our clients are  
managed by Rocks 5.1 so we have the option of using the Mellanox OFED  
roll which includes OFED 1.4.1 I believe. Of course we can also use  
the in kernel OFED with a little more work. Is there a current  
solution that will allow us to build and use Lustre patchless clients  
with the most current RHEL5.2 kernel (2.6.18-164.6.1)?

Thanks,
