--- Comment #9 from Dan Milgram <danm@vivocore.com> ---
I will try to get the first part done tomorrow. Second part (i.e. zdb -l
output) is a little easier so here it is:

root@:~ # zpool import
   pool: zroot
     id: 8676718972300662759
  state: ONLINE
 status: The pool was last accessed by another system.
 action: The pool can be imported using its name or numeric identifier and
    the '-f' flag.
   see: http://illumos.org/msg/ZFS-8000-EY
 config:

    zroot                                           ONLINE
      mirror-0                                      ONLINE
        gptid/b1f0a207-641c-11e4-b9e7-28924a36bc5a  ONLINE
        gptid/b260cfdf-641c-11e4-b9e7-28924a36bc5a  ONLINE
