I have an Ubuntu server that i share Directories via NFS from. Now i have to NFS shares that have been working fine for a while now. I added a third within one of the existing directories, but the problem is that i can see the new share, but when i open it on another computer it shows no files within it. I know that there are files on it because it is simply an external hard drive that is formatted with NTFS. When i plug that hard drive into another computer, i can see the files fine on it. I can also see the files it i navigate to the SMB share that the new share resides in. It is only the NFS share that i cannot see the files in. I will try to draw a quick diagram here to explain better:

Main/Old NFS Share: /mnt/Media (can see all existing files within this directory)
New NFS share within the old one: /mnt/Media/Movies/Christmas (it is simply the files in this Christmas directory that i cannot see)

If this is too confusing let me know, i can reword it.

How do you have it listed in /etc/exports?

It should look something like this:

You will need to have ntfs-3g installed, and be using at least nfs v3, preferably v4....

I have never seen your problem and I use NFS quite a lot.

1) Maybe the recursive sharing is a problem?
Have you tried to disable the old NFS share? Does that make any difference?

2) Are the permission in /mnt/Media/Movies/Christmas in order? Can that user read that folder?

3) Are you using the nfs-kernel-server ? If not you really should!

Need to see your /etc/exports file. If all you did was add a sub-folder to an existing share then you shouldn't have needed to create a new share unless you wanted to share only that sub-folder with certain clients. Are you trying to share both the parent and sub-folder to any particular client having this issue?
