It's slow going. I've compiled a partial list of uberblocks on the old
cache disk - I need to check the on-disk spec to see if there is
anything else in there important that zdb -l doesn't list. I think I
might try and find the newest one from the downed pool and copy it
becuase changing just the guid_sum was insufficient. Alternatively, I
think at least I also need to change the transaction number in the
uberblock to match the rest of the pool and change the label state to
match as well.
