Can mount NAS using CIFS but not NFS

**uwe-bungto** · March 27th, 2014

Either of these fstab entries work for me until lately with a D-Link DNS-321 and two Linux boxes running 12.04 LTS
[CODE]
192.168.0.14:/Volume_1 /mnt nfs defaults 0 0
or

Code:

192.168.0.14:/Volume_1        /mnt          cifs  guest,_netdev,noperm  0  0

Now only mounting possibility is CIFS. The code in each fstab is basically a cut n paste so they should be identical.

The D-Link is quite old and does not support NFSv4

Has there been changes to the NFS structure?

Code:

192.168.0.14:/Volume_1        /mnt         nfs    defaults 0 0
jpb@Maple:~$ sudo mount -av

Last line in your output is quite clear. The server denied your mount request.

That is obvious. The question is why would the server accept the request from one box and deny the request another one? The request is a simple cut and paste into each fstab.

An I the only one that has a problem with a NAS??

Are you sure the NAS is configured with "no_root_squash" or what its equivalent on the D-Link may be? Connections from fstab take place as the root user.
