Question with regards to NFS mount

[George Magklaras]

One explanation (assuming that your NFS handles are not stale and 
probably they are not from what you are writing) is that when you use 
the Gnome File Manager, the userid you are currently logged as and 
invokes the GFM application does not have sufficient privileges to read 
all the subdirs under the exported /nas folder. The df reports the 
result of the export from processes that have permissions to see the 
entire partition and pass the NFS attributes to the client. That is not 
true for the GFM (or any file manager that reads parts of an exported fs 
with certain non global user privileges) and it that case it will 
silently omit from the sum the dirs or files it does not have access to. 
If you open (under GFM) the /nas share you should clearly see that some 
of the dirs are restricted (the icon indicates that with a 'restricted' 
sign), then you should verify what I am saying. On the contrary, if you 
executed the file manager on the server side as root, you should get the 
full story.
