Thanks for the answers.
I am not the sys admin, but I think I can answer both questions:

The strange thing is that other programs work fine with this setup. 

Do you think the problem is in the file system config (it seems so) or in FS config to be able to work with NFS 4? 

I have asked the sys admin for the output of the system-config-nfs, I don't have admin privileges to run it. 

thanks again!

Gari,

At the NMR Center we use NFS v4 without problems with freesurfer.  Is the
SUBJECTS_DIR writable?  Note that in the default freesurfer distribution,
the freesurfer/subjects directory is not writable (contains sample and
template subjects).
