The instructions noted above are now INCORRECT for 9.0 (I have not tried this with 9.1 yet) as you MUST manually put the zpool.cache file in place for it to work correctly (I tried a couple different variations when I first setup my systems a few months ago and learned this the hard way :-) I have *lost* of experience with ZFS under Solaris 10 but am relatively new (about a year) to FreeBSD.
