    Description

      Somehow, o2iblnd in latest master branch (225e7b8) is looking for wrong IB interface.

      # cat /etc/modprobe.d/lustre.conf 
      options lnet networks="o2ib0(ib0)"
      
      # modprobe lustre
      modprobe: ERROR: could not insert 'lustre': Network is down
      

      they are trying to use 'eth0' insetad of ib0. eth0 is notihng configured for o2iblnd though.

            Actually I can push a one line change to fix this if this is needed.

            Can we revert the broken patch in the meantime?

            Just master but we need a bunch of fixes for 2.12 for proper IP alias support.

            Of course you can take the ticket! Do you know how long this has been broken? Is it only master broken or does this impact b2_12 at all?
