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

[Jon Marshall]

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
