PC won't shutdown if I shutdown NAS server with ssh

Streagan2 · 10-14-2016, 02:51 AM

I have a Linux Mint 18 PC (mini i7) and a Western Digital My Cloud NAS server (Debian). I mount the NAS folders with the fstab entries:

Quote:

192.168.0.36:/mnt/HD/HD_a2/shared /mnt/NAS/shared nfs rw,udp,users,vers=3,soft,intr,rsize=8192,wsize=8192 0 0
192.168.0.36:/mnt/HD/HD_a2/matthew /mnt/NAS/user nfs rw,udp,users,vers=3,soft,intr,rsize=8192,wsize=8192 0 0

If I just shut down my PC it shuts down quickly.
If I shut down the NAS server first with:

Quote:

ssh -t root@192.168.0.36 'sudo /usr/local/modules/script/shutdown.sh -h now'

and then try and shutdown my PC the PC hangs. I've tried unmounting my NAS mounts and then shutting down my PC without shutting down the NAS. It shuts down fine. It seems the distinguishing step is shutting down the NAS server with ssh. If I do that it hangs when I then try to shut down my PC. Any ideas? Thx,

What does /usr/local/modules/script/shutdown.sh script contain? Or have you a link to this module maybe?

Basically the PC hangs since it is trying to unmount something that isn't there anymore. If this is your normal shutdown process then you might want to consider using automount. Your shares are automatically mounted when you access them and then unmounted when idle.

There are two ways to automount i.e autofs and a systemd. Both are easy to setup and below is a systemd howto.
