Projects: NFS Version 4 Open Source Reference Implementation

Using NFSv4 Referrals

Suppose you want your server to redirect clients that traverse into the NFSv4 directory /foo to the filesystem /bar on the server

First make sure is NFSv4-exporting /bar, as you normally would.

Then create an exports file that looks like this:

/exports	*(rw,no_subtree_check,fsid=0)
/exports/foo	*(nohide,refer=/

This will only work if there is a mountpoint at /exports/foo. If not (for example, if /exports/foo is just empty), you can create a dummy mountpoint using mount --bind:

cd /exports/foo
mount --bind . .

(This just bind-mounts /exports/foo on top of itself.)

The server must have version 2.6.19, and the client 2.6.20 with Trond's NFS_ALL patches; the latest CITI nfs-utils patches are also required. projects | techreports | press | lab | location | staff Email address
