Thanx for pointing out the typo.
But this was only a retype of what I did, not a verbatim cut&paste.

I've redone this action serveral times since I'm also tracking 
8.2-PRERELEASE on a weekly basis.

 From the error message I concluded that gptzfsboot is available on the 
second disk. But in an odd way, it does not find a valid pool to boot from.
If not, why is it giving me the reported message?

Question is: why is the pool on the second disk not valid/available?
