Zpool import failure, metadata checksum fails 8.0-RELEASE

[Joseph Lenox]

Hello, all--

An unexpected powercycle apparently introduced (thanks to my system's 
RAID controller) metadata checksum errors on the system. Attempts to 
import that pool on any system hangs the command (such that it cannot 
even be killed).

I tried pulling out the OpenSolaris (2009.07) cd that I had on-hand, but 
the livecd couldn't find any of the pools in the system--so no help there.

I'm certain a scrub will fix the metadata problems (with or without 
dataloss, the data isn't critical enough to worry about losing a file or 
ten -- losing everything is more of a pain).

Anyone have any ideas for how I can get this pool fixed? I'm working on 
getting 8.0-STABLE sources downloaded (via cvsup) for testing.
