Yes, you copied layout of first disk in rpool to the second disk, this 
created
partition. Root pool is supposed to be created over partition, not the 
raw device.

You should use this flag in this situation. s2 IIRC is a special
"backup" slice which covers the whole disk.
Don't forget to install grub on the newly attached device.
