Hmmmm...  I just tried typing the following command on my system:
   MOUNT TYPE(*NFS) MFS('192.168.5.7:/home') MNTOVRDIR('/mnt')
          CCSID(*ASCII *ASCII)

I didn't get any errors.  When I went to view the files with WRKLNK '/mnt'
they were all there, I was able to view them, edit them, etc.

That won't matter. the ADDMFS command and the MOUNT command are the same
thing.  They call the same underlying program.

Are you sure that you have an NFS server running on the Linux box?  It
seems peculiar to me that you're using SMB to access the iSeries from the
Linux box, but NFS in the other direction.

Have you tried accessin the iSeries via NFS from the Linux box?  (It works
a whole lot better than SMB, in my opinion!)

I use DNS here instead of the HOSTS table.  I guess that could be the
difference. But, since you're accessing it by IP address anyway, I don't
see why it would matter?  In fact, I just tried ending my DNS server,
running MOUNT again, and it still works even though the host can't be
looked up!

Heh... my experience has been "it just works."  I haven't needed to
troubleshoot anything, because nothing ever goes wrong.

Here are some ideas of things you can check:

a) Make sure the NFS daemon, portmapper, RPC, etc are running on the Linux
box.

b) Make sure that the iSeries has been given permission to mount things
from the Linux box in the /etc/exports file.
