[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 ___ Lustre-discuss mailing list Lustre-discuss@lists.lustre.org http://lists.lustre.org/mailman/listinfo/lustre-discuss

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.

Re: [Lustre-discuss] Seeking LNET router recomendations
I don't think so, because any time two NIDs map to the same node, LNET will pick a 'best' interface (based on hop count and other things) and always use that interface. In the normal case, you would subnet to separate the interfaces and use both, but you can't in this case as ib0 is the same IP for boh. Really would be best to have a second IP for TCP. cliffw On Wed, Mar 28, 2012 at 9:01 AM, Hayes, Bob bob.ha...@intel.com wrote: When we added ‘options lnet networks=o2ib(ib0),tcp1(ib0)’ to the MDS and the OSS’s, communications from the nodes using tcp1 would not be returned by the OSS’s.

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 joh...@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.

Re: [Lustre-discuss] Latest RHEL/CentOS kernel that compiles against Lustre 1.8 git tree?
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.
