[zfs-discuss] cannot import ''rpool'': one or more devices is currently unavailable

I have a system who''s rpool has gone defunct. The rpool is made of a 
single "disk" which is a raid5EE made of all 8 146G disks on the box. 
The raid card is the Adaptec brand card.  It was running nv_107, but its 
currently net booted to nv_121. I have already checked in the raid card 
bios, and it says the volume is "optimal" . We had a power outage in 
BRM07 on Tuesday, and the system appeared to boot back up, but then went 
wonky. I power cycled it, and it came back to a grub> prompt cause it 
couldn''t read the filesystem.

I obviously have no clue how to weild zdb.

Any help you can offer would be appreciated.

We''ve been able to recover pool by rolling back a few uberblocks - only
a few log files had errors. Uberblock rollback project would allow to 
recover in this case quite easily.
