unable to mount one spezific nfs share on Mac

Hi,

I have 8 NFS shares on the OMV, all with the same privileges and options.
On the Mac shell I can mount any of these nfs shares on the Mac. Therafter I am able to access any of the mounted folders by 'cd..' or with the finder except one spezific folder (it's the largest with videos). Changing the mount point has also no effect.
When I want to 'cd' into that folder, it says 'permission denied', using the Finder that folder shows empty.

Apple filing and SMB with that folder is working.

Any ideas?

Thanks!
Andy

I finally found out myself:

I passed 'chown -R....' command onto the entire folder. That's it.
