Thanks, that was exactly what I needed to dig out the bad modules!

Kurt,

I see you're using dkms. Take a look at `dkms status` and ensure that there are no lingering installs from the previous version. Sometimes the older version doesn't get uninstalled from /lib/modules/`uname -r`/ and the dkms install process for the new version doesn't overwrite them.

Good Morning,


   I've encountered an issue updating lustre from 2.10.6 to 2.10.7 on my metadata system.


I installed the updated RPMs using whamcloud's yum repository, but when I run modprobe -v lustre I get the following errors:

I've tried uninstalling and reinstalling the RPMs but this is always the state I end up in.


I'm using zfs for the back end, and those modules work after the upgrade


Here are the RPMs currently installed.

perf-3.10.0-957.1.3.el7_lustre.x86_64
lustre-resource-agents-2.10.7-1.el7.x86_64
lustre-osd-zfs-mount-2.10.7-1.el7.x86_64
