These are the output of the command on my system after hangs. but why
I saw nothing about my NFS directories?

I added the script to the path, and the system shutdown correctly, but
the time is too long, every NFS directory complained the timeout due
to and then umounted, maybe it took about 10 minutes for choosing the
shutdown under desktop to the system poweroff automatically.
