As Martin notes below, the above does not export any file system.
Add a line for /usr/archive/Shared to /etc/exports just like you would
have for UFS and then send a HUP signal (kill -HUP <mountd-pid>) to
make the changes to /etc/exports take effect.
- After this, check for syslog messages, in case the exports syntax
isn`t correct.
I know nothing about ZFS, but my understanding is that you can do
everything in /etc/exports just like you would for UFS.
(I'm not even sure what ZFS calls a file system, but every line
you see when you type "mount" with no arguments is a file system
as far as FreeBSD is concerned.)
Every file system you want to access from client(s) must have an
line in exports (or in the ZFS stuff if you choose to do it that way).
The only difference for NFSv4 is that the client(s) don`t have to
do separate mounts for each file system, but they all must be
exported to the client(s).
Hope this helps, rick
ps: You only have one V4: line because there is only one place
in the server`s directory tree that can be a root for NFSv4.
