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.
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.

I obviously have no clue how to weild zdb.
Any help you can offer would be appreciated.
