And config/lustre-build.m4 should then also be reverted regarding the above commit.</p> <p> </p> <p>There is also another problem when using Mellanox OFED 4.4 DKMS built kernel modules.</p> <p>/usr/src/ofa_kernel/default doesn't exist in the mlnx-ofed-kernel-dkms package, it is only created (as a link) during package installation. Therefore the</p> <p>O2IBPATHS=$(eval $OFED_INFO | egrep -w 'mlnx-ofed-kernel-dkms|mlnx-ofa_kernel-devel|compat-rdma-devel|kernel-ib-devel|ofa_kernel-devel' | xargs $LSPKG | grep '&#40;/openib&#124;/ofa_kernel/default&#41;$' | head -n1)</p> <p>in lnet/autoconf/lustre-lnet.m4 fails.</p> <p> </p> <p>The attached patch fixes the problem (assuming the LB_USES_DPKG block has been put back)</p> Ubuntu with Mellanox OFED 4.4 LU-11541
