Lustre discuss - Feb 2009 - query about support of new redhat kernels

Hello all,

I spent the day tracking down my NFS lockd hangs that I''m seeing on a  
RHEL5 server, and finally found them described in this errata from  
Sept of 2008:

	http://rhn.redhat.com/errata/RHSA-2008-0885.html

The fix is in the RHEL5 kernel 2.6.18-92.1.13. I see that the latest  
Lustre RPMs are at 2.6.18-92.1.10; I''m curious how often the RHEL5  
RPMs are updated to track the kernel bugfixes.

I''m guessing short term I will have to rebuild my RHEL kernel from  
sources, or use the patchless kernel. (The machine in question is  
currently an NFS server for a bunch of bioinformatics pipeline job  
data; we are in the midst of acquiring a Lustre server to host this  
data, and in the meantime I have a small test Lustre server cluster  
set up which is why I''ve got the Lustre kernel on it).

thanks for any advice,
--bob

We update kernels regularly. 1.6.7 will support 2.6.18-92.1.17.el5,
the development branches (like b1_6 or b1_8) use 2.6.18-92.1.22.el5
and we are working on RHEL5.3 support (see bug 18289).
