Right, and we're OK with that.. We were lucky - all of the corrupt files are
non-essential. When I remove the files and replace them, I get something that
looks like a hex device:block number (ie: <0x86>:<0x38fcd>).
The server is a v440, so I was able to have someone add some extra drives.

If I delete one of these files, zpool status -v shows that device/block
identifier I mentioned previously.. I've run a few scrubs, but they don't
change anything.
The system appears stable right now, our internal customers have no idea
anything is wrong (IE, their apps are stable). We're planning on migrating them
to a Niagara blade to return things to "known good".
I'm still curious to know if anyone knows a fix for this kind of issue, if
there is one. I fully expect that if I was running UFS on one drive and it
failed like this zfs drive failed the system would have panicked. That's a
big win. I would still like to get to the bottom of this issue. :-)
Thanks again for your replies.

Hey Kris (glad to see someone from my QCOM days!):
It should automatically clear itself when you replace the disk. Right
now you're still degraded since you don't have full redundancy.

Hi Folks..
I have a system that was inadvertently left unmirrored for root. We were able
to add a mirror disk, resilver, and fix the corrupted files (nothing very
interesting was corrupt, whew), but zpool status -v still shows errors..
Will this self correct when we replace the degraded disk and resilver? Or is
there something else that I'm not finding that I need to do to clean up?

Thanks for any suggestions. The system is in another city, so I can't quickly
test replacing the disk and see what happens..
