I'm trying to do this "simple" thing:

- Directory /export/rw is exported with read-write for a subset of
servers (server1, server2, server3)
- The same directory needs to be Read-Only for all servers, including
server1, server2, server3 (more than 200 servers in read-only)

You cannot export the same directory twice. What I did:

ln -s /export/rw /export/ro

and then I exported the /export/ro as read-only. Many tests later, I
found that only server1, server2 and server3 can mount /export/ro!!!
It is as if AIX export only the "real" directory, no matter on many
links I put.

Any ideas, any suggestions?

What I really want to do: permit only a subset of server to write to
this directory, but any server can read it. This space will contain
"configuration files", and I want to be sure that only the servers I
control can write to this directory. I don't care if any servers, or
linux workstation, or Windows with Unix services access it to read the
content.

Thanks.
