Well, I'm not absolutely sure I'm right, but I wrote this
a few months ago having the "nfs: stale filehandle" issue:

  I had some trouble with a "nfs: stale filehandle"
  because I was quite clueless and I thought that
  sharing /var/lib/nfs was the only important thing,
  but that's not the case. You must share the raw
  exported filesystems using drbd. Period. The inode
  numbers must be the same on the main server
  and in the backup server.

So I guess that if your exported filesystem is read-only,
you would have to replicate it using a low level tool such as
dd, and not "cp". I haven't tried.

I'd like to know whether I'm right or not.

Regards.
