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

LU-1052 is the jira ticket for 2.6.18-308.1.1 support. There is a patch here which should help you to build against this kernel.

Hi Jeff:
Our 2.6.32.58.scalable kernel has been patched for 1.8.+ git. 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.
Regards,
Joe

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... :)

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.

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.

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.
