NFS4 "Cross Device" Problem

[David Cary Hart]

The server has /var mounted on a separate SCSI drive.

Exports are fine. I have two insecure exports to 192.168.0.0/24; / and
/var.

Mounting server:/ works perfectly. If I try to mount /var on a client
machine, I get a message that the "special device" does not exist. The
server log indicates that the file handles of / and /var are duplicated.

While the root directory "/" works perfectly (export and mount), it does
not provide access to /var, presumably because it is not on the same
partition (??).

I tried a soft link on the server (nfsvar -> var) as a work-around.
However, from a client that ends up linking to the local /var directory.

Any ideas?
