Yes, it is possible to have a file system exported on a read-only basis
to some nodes and read-write to others, but not in SGI release 3.6 for the
3000 series. This enhancement to exporting did not appear until Sun's 4.0
release and SGI's 4D3.1 release.
The new /etc/exports format allows you to specify:
/usr/src -rw=hostA:hostB:hostC
which gives hostA, hostB, and hostC read-write access to the server's
/usr/src tree and read-only access to everyone else. See exports(4),
rw= option, and exportfs(1M).
It should be noted that using multiple entries for a given file system in
/etc/exports in an attempt to export to different clients with different
options is not supported. If you'd like more detailed information as to
what is going on, you can look at /usr/adm/syslog which is where mountd
reports its problems.
