Sometimes it takes a little while for the remount to happen
automatically, but that wouldn't be a "permission denied."  (For a while
I had kernel panics on my fileserver...)

/etc/exports on server:
/home/mythtv/data 192.168.0.0/255.255.255.0(rw,no_root_squash,async)

/etc/fstab on backends:
192.168.0.2:/home/mythtv/data   /home/mythtv/data       nfs
bg,hard,intr,tcp,nfsvers=3,rsize=32768,wsize=32768,noatime,actimeo=0    0 0

I can't even remember how I worked up those parameters for mounting - I
suspect a lot of it was culled from this list, plus some
trial-and-error.  Works For Me (tm)!
