How to stop Lustre client service?

I fail to reconnect the machine via ssh as usual after I reboot it. Then I check the machine physically, and find the reason:

LNetError: 131-3: Received notification of device removal
Please shutdown LNET to allow this to proceed
INFO: task reboot: 30396 blocked for more than 120 seconds.
Please shutdown LNET to allow this to proceed

Please shutdown LNET to allow this to proceed

It seems that we need shutdown LNET(Lustre service) before we execute the reboot command. So I run the below commands to shutdown/stop Lustre service.

# umount /lustre
# lustre_rmmod

Now, everything is OK.
