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

Hi,
I'm in the process of rebuilding lustre on Rocky 8.10 and have noticed that
NVIDIA have been messing around with their packages again, now rebranding
everything under the doca label. 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.
The trouble is, it seems they have rename the package mlnx-ofa_kernel-devel to
mlnx-ofa_kernel-dkms. Looking at the DKMS configure script, it is searching for:
O2IBPKG="mlnx-ofed-kernel-dkms"
O2IBPKG+="|mlnx-ofed-kernel-modules"
O2IBPKG+="|mlnx-ofa_kernel-devel"
O2IBPKG+="|compat-rdma-devel"
O2IBPKG+="|kernel-ib-devel"
O2IBPKG+="|ofa_kernel-devel"
And hence it can't find the package (underscore instead of hyphen), which
causes the build to fail.
Digging around the JIRA, I found
this<https://jira.whamcloud.com/browse/LU-18002?jql=text%20~%20dkms%20ORDER%20BY%20created%20DESC>
issue, but it looks to only have been fixed in 2.16, which we've sort of ruled out at this
stage. 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.
I can work around by building things myself, but I was hoping to be able to yum
install the packages direct from the whamcloud repos, as this greatly
simplifies my rollout.
Cheers
Jon
