Hi list,
Today I needed to shut down my home server (FreeSBD9-CURRENT, 3 x 40GB 
ATA HDD in RADZ1, ZFS only, GPT, i386) for a moment. After power up, 
loader started to spin cursor indifinitely, and didn't load the kernel. 
No error messages, no hints, just spinning cursor.
I tried booting from other HDDs in case that bootstrap area errors on 
single hdd but no luck.
I wanted to play with latest current LiveFS snapshot (with ZFSv28 
support), but apparently latest one is from february??
Finally I ended with mfsBSD from http://mfsbsd.vx.sk/
I've downloaded "8.2-RELEASE-i386 with ZFSv28 special edition 
<http://mfsbsd.vx.sk/iso/mfsbsd-se-8.2-zfsv28-i386.iso>" iso, burned it 
and booted machine. Here's what happened when i was trying to import zpool:

    mfsbsd# zpool status
    no pools available
    mfsbsd# zpool import
       pool: zroot
         id: 16074929158756467860
      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://www.sun.com/msg/ZFS-8000-EY
    config:

             zroot                                           ONLINE
               raidz1-0                                      ONLINE

                 gptid/87d467cc-bc3b-11df-8066-0050dad823cd  ONLINE
    mfsbsd# zpool import -f zroot
    cannot import 'zroot': one or more devices is currently unavailable

There was also some kernel messages while running zpool commands, they 
are visible at the end of dmesg output:

Any idea what happened to the pool, why I am unable to boot and import 
it, and what can I do to investigate or fix this issue?
