I am trying to set up my pi3 running raspbian as an NFS server. I've followed these instructions: http://www.htpcguides.com/configure-nfs-server-and-nfs-client-raspberry-pi/

In /etc/exports I have the line:

/mnt/Shared 192.168.1.0/24 *(rw,sync)

Which I hope means that the folder at /mnt/Shared (which is a directory on an external hard drive) is available for reading and writing by all machines using a local IP address. Then I do exportfs:

$ sudo exportfs
/mnt/Shared    192.168.1.0/24
/mnt/Shared    <world>

Then, on my laptop, which is running Ubuntu, I follow the client side instructions from the same site, but the mount command fails after a long wait:

$ sudo mount 192.168.1.105:/mnt/Shared /mnt/nfs
mount.nfs: Connection timed out

If I try that verbose it looks like this:

sudo mount -v 192.168.1.105:/mnt/Shared /mnt/nfs/
mount.nfs: timeout set for Sat Feb 18 21:52:14 2017
mount.nfs: trying text-based options 'vers=4,addr=192.168.1.105,clientaddr=192.168.1.109'
mount.nfs: mount(2): Connection refused
mount.nfs: trying text-based options 'vers=4,addr=192.168.1.105,clientaddr=192.168.1.109'
mount.nfs: mount(2): Connection refused
...
<repeated several times>
...
mount.nfs: Connection timed out

Has anyone any ideas of how to make it work? I don't think the problem is with the external hard drive, it appears to be mounted correctly, and I had the same issues trying to share a local directory.

  • I've got it to work! A commenter on this question (raspberrypi.stackexchange.com/questions/48091/…) suggested trying "sudo systemctl restart nfs-kernel-server" after each reboot of the system, and since I've done that it seems to work. I need to figure out how to make that happen automatically after each reboot. Once I've done that I'll add it as an answer, unless someone has a better solution in the mean time. – EddyTheB Feb 19 '17 at 11:15

    I'm not sure the result of the exportfs is remembered across boots. Try putting the exportfs data in /etc/exports or under /etc/exports.d. There should be no need to restart nfs-kernel-server if the nfs configuration files are correct. – Chad Farmer Feb 23 '17 at 19:17

First I would make the following bash script and call it delay:

#!/bin/bash
# $1:delay time(s)
# $2:command
# example:
#    delay 10 "conky -d"

sleep $1
exec $2

Then I would make it executable

chmod a+x delay

You could put the command from your comments:

delay 60 "sudo systemctl restart nfs-kernel-server"

at the end of the rc.local file in /etc/init.d/ to have it run 60 seconds after every time the Pi boots up

  • Thanks for the tip, but I'm afraid it doesn't seem to be working. After a reboot the drives still wont mount until I run the command myself through ssh. – EddyTheB Feb 20 '17 at 7:13
  • @eddytheb I've made an edit to my answer can you please try it now? – Mohammad Ali Feb 20 '17 at 15:47
  • Thanks again, but I'm afraid it still doesn't seem to be working. Your delay script works, but when I reboot the pi I still have to ssh in and run the restart command myself before the folder becomes visible (even after waiting much longer than a minute). – EddyTheB Feb 20 '17 at 18:15

On the RPi NFS Server (The Media Server)

sudo /etc/init.d/rpcbind restart
sudo /etc/init.d/nfs-kernel-server restart

On the RPi NFS Client (My Plex Server)

sudo mount 192.168.1.105:/mnt/Shared /mnt/nfs

This worked for me.

And I had to mount my drives including the uid/gid in /etc/fstap because in my case chown does not work when the drive is mounted by root. Maybe someone can give me a tip for that.

Tell reboot to wait for the network to be available. It’s on raspi-config in the advanced section iirc
