So... I do appear to have reached somewhat of a truce with the system and
b126 at the moment. I'm now going through and replacing the last of my old
maxtor 300GB drives with brand new hitachi 1TB drives. One thing I'm
noticing is a lot of checksum errors being generated during the resilver.
Is this normal? Furthermore, since I see "no known data errors", is it safe
to assume it's all being corrected, and I'm not losing any data? I still do
have a separate copy of this data on a box at work that should be completely
consistent... but I will need to re-purpose that storage soon, and will be
without a known good backup for a while (I know, I know). I'd rather do a
fresh zfs send/receive than find out 6 months from now I lost something.
