Weird. You don't describe what kind of HA
solution you're setting up.
Does it work at all?
Are you using DRBD?
I've only set up 1 HA-NFS server using DRBD and I
got the stale filehandle issue on failover. It would last
a few seconds.

I also used nfs-kernel-server.
I would get the stale filehandle on failover until I
patched the nfs-kernel-server init script.
