[Lustre-discuss] Problem with LNET and openibd on Lustre 1.8.4 while rebooting

I guess the trick is to use _netdev as an option in the mount command or the /etc/fstab entry as Andreas mentioned.

I used to have the _netdev option when I was using Lustre over ethernet which made the automounts work correctly and I didn't have the LNET problem.

With infiniband(openibd) the _netdev option doesn't mount lustre correctly and I had to mount lustre from rc.local after the infiniband networks comes up.
