Please send the output of "camcontrol devlist" and "zpool status" on
FreeBSD-8.1.  Then export the pool in FreeBSD-8.1, boot FreeBSD-9 with
verbose booting and send the output of "camcontrol devlist", "zpool
import BACKUP" and the part of /var/log/messages that shows FreeeBSD
searching for the pool during the import.

It might be useful to know what disk controller is being used.

It is not related to your problem, but how did that unused space wind up
before partition 1?
