I’m not sure what you mean by “shows as partial”. I can’t find a (systemd) lustre.service file that is packaged with the community Lustre. Did you create your own? I would say it is good practice to load the modules even though it shouldn’t be strictly necessary. Performing a “mount -t lustre…” should pull in any necessary modules. If that isn’t happening maybe you just need to run depmod.

Thanks for the info. Finally, I was able to install lustre servers (MGS and MDS) as of now. I used native IB drivers which came with RHEL 6.7 My question is do I need to run modprobe lustre and modprobe lnet everytime lustre server reboots? What I observed that service lustre start doesnot come up without modprobe lustre. Any suggestions?

If you’re using the MOFED drivers you’ll need to recompile Lustre.

My ib0 is working fine and I can ping other nodes. my lustre.conf file has options lnet networks=o2ib(ib0) With this, If I run “service lnet start” it fails with error LNET configure error 22: Invalid argument dmesg give me output as below (I just captured last line but there are many lines with symbol error or so) LNetError: 16770:0:(api-ni.c:1276:lnet_startup_lndni()) Can't load LND o2ib, module ko2iblnd, rc=256 If I specify tcp in lustre.conf,, it works fine.

Now I am also trying with RHEL 7.3 and Lustre 2.10.0. I am planning to install Mellanox OFED driver with 3.4 stack. Looks like there is some problem with OFED 4.x stack with Lustre 2.10.0. Let me try the same and update. When I start “service lnet start” it gives LNET configure error 22: Invalid argument but it works fine with tcp.
