Hi Roland, Thanks for your answer. Here are answers to your questions: There are two things here that make me wonder though: a) You don't have an option like --with-linux=${KSRC} no I don't use that option, which make no differences since the configure script uses /usr/src/linux-source-3.2.0. I tried the option --with-linux=/usr/src/linux-source-3.2.0 b) What's underneath /usr/src/mlnx-ofed-kernel-2.0? Makefile@ compat/ compat_base_tree compat_version dkms.conf include/ net/ backports/ compat_base compat_base_tree_version configure@ drivers/ makefile@ ofed_scripts/ I did a little hack for a test: I replaced the two occurences of "ENABLEO2IB=3" by ENABLEO2IB=1 in the configure script after reading a couple of threads found on Google. That make the compile work without error, but the o2ib network returns error 100. mel-bc1e41-be14:~# cat /etc/modprobe.d/lustre.conf options lnet networks=o2ib(ib0.8002) and here is what I get when I try to start lnet: mel-bc1e41-be14:~# modprobe lnet mel-bc1e41-be14:~# lctl network configure LNET configure error 100: Network is down And the syslog reports this: Dec 16 12:11:34 mel-bc1e41-be14 kernel: [ 231.667631] LNetError: 2766:0:(api-ni.c:1227:lnet_startup_lndnis()) Can't load LND o2ib, module ko2iblnd, rc=256 the tcp network works fine with the client compiled that way, Thanks!

--------------------- Support for networks: o2iblnd - OFED 1.5.4 --------------------- Red Hat kernel might support newer stock and Mellanox OFED https://jira.hpdd.intel.com/browse/LU-2975 With the Ubuntu 3.2 kernel you're probably out of luck (without investing more time). The build process in newer OFED releases has changed considerably since they are using the compat-rdma framework. You could try using vanilla 3.12.5 client with mentioned fixes or the kernel packages from Qlustar.
