[Lustre-discuss] Latest RHEL/CentOS kernel that compiles against Lustre 1.8 git tree?
Greetings, Does anyone know the most recent kernel (RHEL/CentOS) that can be successfully patched and compiled against the current Lustre 1.8 git source tree? I attempted 2.6.18-308.1.1 but there are several patches that fail. Quilt would not make it past the third patch in the series file. Applying the patches manually reveals several hunk failures. I require a kernel more recent than 2.6.18-274.3.1 for non-Lustre related issues. Thanks in advance. -- ------------------------------ Jeff Johnson Aeon Computing jeff dot johnson at aeoncomputing.com www.aeoncomputing.com 4905 Morena Boulevard, Suite 1313 - San Diego, CA 92117

We could use some testers to help us out. We''ve integrated the Lustre patch process into our build environment, and fixed the few small issues we''ve found. Happy to have more testers if you are interested.

I applied that patch at 9AM this morning. Several hunks failed and then I noticed that the LU-1052 patch is literally morphing as the morning progresses. There is a difference between living on the bleeding edge and standing in a field watching the razor''s edge coming at you... :) On Thu, Mar 29, 2012 at 11:40 PM, Johann Lombardi <johann at whamcloud.com> wrote:> On Thu, Mar 29, 2012 at 11:30:03PM -0700, Jeff Johnson wrote: >> Does anyone know the most recent kernel (RHEL/CentOS) that can be >> successfully patched and compiled against the current Lustre 1.8 git >> source tree?

Heh. Nice imagery Jeff. Yes, this patch is still under active development and also note that it will not be able to complete autotest until we switch it to use RHEL5.8 by default (hopefully soon, but this had been on hold until we saw whether we needed RC3 for 2.2). So, if you are willing to test the latest patch that would be appreciated and could accelerate things (please post your findings on the JIRA ticket), but regardless we should have this work completed in the near future.

My Lustre system (IB, Xeon-E5, 4xOSS, 4xOST, 84TB, 16 clients) is a development only system. No meaningful data. It is currently loaded with CentOS5.8 and I have Lustre 1.8 source checked out via git last night. I''m happy to test and provide feedback. FTR, I think Intel''s new isci driver is a real PITA.

FYI, I tested the Lustre 1.8 patch that provides support for 2.6.18-308.1.1 and while it does successfully compile the resulting changes in the kernel severely impact the isci (Intel SAS) driver. Romley (new Xeon-E5) systems booting this driver panic during boot, just after switchroot. I will capture the trace and post it, it appears to be the result of patch changes to jbd. --Jeff On Fri, Mar 30, 2012 at 11:41 AM, Peter Jones <pjones at whamcloud.com> wrote:> Heh.

Would you mind giving a try to the updated patch to check if your problem is fixed? Cheers, Johann -- Johann Lombardi Whamcloud, Inc. www.whamcloud.com
