problem accessing USB drive on nfs server from a client

Question

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.

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
