[LU-101] building Lustre against OFED when the kernel has built-in IB causes symbol mismatch

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Affects Version/s: Lustre 1.8.6
• Severity: 4

Description

When building 1.8.x against out-of-kernel OFED and a Lustre kernel with in-kernel IB support, Lustre will pick up the IB symvers of the kernel. The workaround is to remove all references to IB in the kernel module.symvers, but it's a confusing step. It would be nice if Lustre did the right thing here and preferred the --with-o2ib symvers over the kernel symvers. I thought that there had been some work on this in the past, but it seems to not have stuck, as we still run into this issue regularly.

Thanks,
Kit

On an administrative note: Which should we use to mark how important a bug is? Priority or severity? This issue is not at all critical since there is a well understood workaround and it doesn't affect anything except the build process.
