So my server is at 192.168.0.15

the client is at 192.168.0.17

(Both machines have a user called 'work')

On the server, my USB HDD auto mounts as /media/work/EXT4-4TB

I'd like to access this from the nfs client, so, on the server my /etc/exports contains:

/media/work/EXT4-4TB 192.168.0.17(rw,sync,no_root_squash)

To start the nfs server I run:

$ sudo systemctl start nfs-kernel-server.service

On the client I have an empty directory set up at /home/work/archive/

But when I try and access the share with:

$ sudo mount 192.168.0.15:/home/work/EXT4-4TB /home/work/archive/

I get:

mount.nfs: access denied by server while mounting 192.168.0.15:/home/work/EXT4-4TB

I can access other nfs shared directories on this server, but the difference seems to be that this one is over USB.

I'm thinking it's something to do with the auto-mount or permissions but am out of ideas at this point on how to fix the problem.

Help would be appreciated.

    I just noticed your paths are wrong after posting my response below. You are exporting /media/work/EXT4-4TB but on your client you are trying to mount /home/work/EXT4-4TB. You can mount the USB in fstab into /home/workusing step #2 in my response below. Try using sudo mount 192.168.0.15:/media/work/EXT4-4TB on the client as well if you want to narrow down the source of the problem. – m_krsic Jan 10 '18 at 16:25
  • Embarrassing. That was the problem :( – Thorsen Jan 10 '18 at 20:06

Try the following

  1. sudo blkid to get the UUID of the USB drive
  2. Add an entry to /etc/fstab to make the drive mount the same way every time, use the UUID instead of the /dev/sdX path, mount it in /mnt instead of the temporary /media folder
  3. Add the new mount path to your /etc/exports
  4. sudo exportfs -ra to load the new NFS settings

    Although, my typo was to blame, this looks like a better way to deal with this. I will mark the question as answered. Thank you for the help. – Thorsen Jan 10 '18 at 20:09
