Hi,
I'm running FreeBSD 7.1-PRERELEASE with a 500-gig ZFS drive. Recently I've
encountered a FreeBSD problem (PR kern/128083) and decided about updating the
motherboard BIOS. It looked like the update went right but after that I was
shocked to see my ZFS destroyed! Rolling the BIOS back did not help.
Now it looks like that:
# zpool status
pool: tank
state: UNAVAIL
status: One or more devices could not be used because the label is missing
or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from a backup source.
see: http://www.sun.com/msg/ZFS-8000-5E
scrub: none requested
config:

I've tried to import the problem pool into OpenSolaris 2008.05 with no success:
# zpool import
pool: tank
id: 12069359268725642778
state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
see: http://www.sun.com/msg/ZFS-8000-EY
config:
tank UNAVAIL 0 0 0 insufficient replicas
c3d0s2 UNAVAIL 0 0 0 corrupted data

Is there a way to recover my files from this broken pool? Maybe at least some
of them? The drive was 4/5 full. :(
I would appreciate any help.
p.s. I already bought another drive of the same size yesterday. My next ZFS
experience definitely will be a mirrored one.
