<p>Just for public reference the solution was provided by Martin
Audet which was to add the --kmp flag when building MOFED. So you
want:</p>
<p>mlnxofedinstall --add-kernel-support-build-only --kmp</p>
<p>Thanks Martin!<br>

<div class="">I'm working on building Lustre 2.15.4 against
recent versions of Mellanox OFED. I built OFED against the
specific kernel and then install mlnx-ofa_kernel-modules
for that specific kernel. After which I built lustre
against that version of OFED using:<br class="">
<br class="">
rpmbuild --rebuild --without servers --without mpi --with
mofed --define "_topdir `pwd`"
SRPMS/lustre-2.15.4-1.src.rpm<br class="">
<br class="">
However once I finish building and install I get:<br

I saw this earlier message which matches my case: <a

Does anyone know the solution to this? Is there a work
around?<br class="">

You probably need to "rpm -Uvh" instead of "rpm -ivh" the new
kmod-mlnx-ofa_kernel RPM?
<div class=""><br class="">
</div>
<div class="">Or, if you want to keep both RPMs installed (e.g.
for different kernels) then you can probably just use "--force"
since it looks like the .conf file would likely be the same from
both packages.
