I believe the order when shutting down should be to
1. umount the FS
2. lustre_rmmod
3. reboot/shutdown

There should be an lnet script

/usr/lib/systemd/system/lnet.service 

That script should do the above steps.

It'll be a matter of making sure that this script is executed (IE lnet service stopped) on shutdown before the OFED modules are unloaded.

Is there a recommended init script to shutdown lnet ??

[Amir Shehata (Inactive)]

It appears that OFED is being shutdown before LNet. This would cause LNet to get stuck. So in your shutdown procedure LNet should be shutdown before OFED.
