Hi,

I was under the impression that nfs exports a filesystem in its entirety.
Therefore, if you have another filesytem mounted in a subdirectory, you
have to export it too, as it will not be exported for you. You therefore
might have to have two entries:

/data/shared/   172.16.1.0/255.255.255.0(sync,rw,nohide)
/data/shared/Photos/Archive1   172.16.1.0/255.255.255.0(sync,ro)

I hope that helps. If nohide does not work, then you will have you use two
mounts on the clients.
