Hi!

This is my root pool, is it exported on shutdown? i would think so..

I think, if i move the mirror drive to a different slot and leave the
origin-slot empty, it could work..

I should have imported and exported the pool with a illumos-live-USB, 
_before_ trying to boot the installed system with the change.

i had no live-medium at hand so i just gave it a try..

BTW, the mirrored pool is up and working:

$ zpool status rpool
  pool: rpool
