I think that the file zpool.cache is missing or it contains pool data coming 
from the USB stick you used. I wrote an article for this, but unfortunatelly 
is in Greek... The article is here: 
http://www.freebsdworld.gr/node/38#zpool_cache
Besides the problem that you will not understand what I write (:)) you can 
follow the commands. You will probably understand what's happening there. Just 
skip the part that I cange the names of the gpt partitions (the one that I 
have a bunch of "gpart modify" commands)

I hope it will be usefull to you

Elias
