I have recently finished my NFS setup and it has been working so well that I ran out of space (1TB) . That's not really a problem because I was prepared for it. Its because I'm moving everything off my Windows infrastructure so I can fully migrate to Ubuntu.
I have put a USB hard drive on the server with an extra 1.5 TB of space and mounted it in a folder on the share. So my set up is like this
I have shared out a folder from the ubuntu server using NFS called /Shares.
Inside /Shares I have many folders but one of them is called /Shares/Video/TV Shows (can you guess what's on it 
When I'm using Files or on the terminal directly on the server and browse to /Shares/Video/TV Shows it gives me /dev/sdb1 without a problem however when I use another computer and go to it using NFS, I get the mount directory itself instead of the drive mounted on the directory.
Its probably something very simple that I'm doing wrong.
Does anyone have any advice?
Here's my fstab and exports to show what I mean
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/mapper/ubuntu--vg-root / ext4 errors=remount-ro 0 1
# /boot was on /dev/sda1 during installation
UUID=74f35fcd-ea46-4923-8671-d74f374b2538 /boot ext2 defaults 0 2
/dev/mapper/ubuntu--vg-swap_1 none swap sw 0 0
/dev/sdb1 /Shares/Videos/TV\040Shows auto nosuid,nodev,nofail,x-gvfs-show 0 0
and here is my /etc/exports
# /etc/exports: the access control list for filesystems which may be exported
# to NFS clients. See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)
#
/Shares *(rw)
NFS multi drive ?
