Also I'm not sure if showmounts output would show this, but is the (options)
after ip address required?  For instance, cat /etc/exports would give:

	/media/vol2 0.0.0.0/24(rw)

If that still doesn't work, you could try

	/media/vol2 (rw)

to check whether addressing is the problem.  But I think we'll need to
see whether there are any relevant messages in /var/log/syslog.

(You're using the nfs kernel server, right?)
