Hi Matt, if you can remember the status information and are the only administrator, you can just doa zpool clear and re-scrub your pool regularly. zpool clear does no more or less than resetting the status and the counters. (A reboot or export does the same thing, at least no Mac OS X.) The point is that all errors have been corrected. All errors are accumulated until you do a clear. If you want to know how well your disks work, the easy way is to do a zpool clear followed by a scrub. If you continue to see checksum errors, you might want to conside replacing your disk, ralf
