[LU-345] kernel and lustre version miss match for RHEL6

• Status: Resolved

Description

Install lustre-master/RHEL6-x86_64 build with loadjenkinsbuild, kernel and lustre version miss match. Have to do insmod manually to install lustre modules.

For example, installing build #125 on fat-intel-1, lustre modules are under /lib/modules/2.6.32-71.18.2.el6_lustre.gce09fce.x86_64

[root@fat-intel-1 ~]# uname -a
Linux fat-intel-1.lab.whamcloud.com 2.6.32-71.29.1.el6.x86_64 #1 SMP Thu Apr 21 16:08:55 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux
[root@fat-intel-1 ~]# ls /lib/modules/
2.6.32-71.18.2.el6_lustre.gce09fce.x86_64 2.6.32-71.29.1.el6.x86_64

Can you please look at this one?

Thanks

This appears to be a problem with the EL6 installer. In short, even though the kickstart is specifying the correct kernel, EL6 is choosing the newest kernel it sees. This wasn't a problem until I added the latest errata kernel to the local yum mirror for EL6 (for LU-343).

As a short-term kludge, I can remove the 2.6.32-71.29.1.el6 kernel. Longer-term, this is a bug in EL6 (or a change in behavior that I consider a bug). I'll poke around in RH's bugzilla to see if this is a known issue which may have been addressed in EL6.1.

I've taken the kludgy approach for now and removed the 2.6.32-71.29.1.el6 kernel RPMs from the local mirror. I'll try to find a better solution soon, as this problem hinders our ability to test multiple kernel versions.

This ticket and TT-136 are basically for the same issue. As that ticket has been resolved, this one should be as well.

got this issue again on the latest tag 2.0.66 build #228

[root@client-15 tests]# uname -a

This is due to the requested EL6 kernel update. Due to the way EL6's anaconda works now, it is not possible to specify that an older kernel should be installed when a newer one is available in the repos.

This is no longer an issue.
