[lustre-discuss] DKMS build broken with NVIDIA doca packages

[Mark Dixon]

Hi Jon,

As it happens, I've been looking at the same thing. I hadn't spotted 
LU-18002 (thanks), but unfortunately it isn't enough to accommodate the 
move to dkms on rhel.

I don't know how far you've got since Monday, but there now seems a need 
for an explicit check of /usr/src/ofa_kernel (as it's no longer owned by a 
package) and the "find" for rdma_cm.h needs the -L flag to make sense of 
the new maze of twisty passages.

I think that a new jira ticket needs to be opened...

Cheers,

Mark

For LTS purposes we're sticking with 2.15.8 for lustre, and I'm trying to get this to build with NVIDIA DOCA 3.2.1 LTS.

Looking at the actual patch<https://review.whamcloud.com/c/fs/lustre-release/+/55625/4/lnet/autoconf/lustre-lnet.m4>, it seems pretty minor and I was wondering if this could be back ported to 2.15 as well.
