Just another case where my "keep it small enough to be maintainable" policy triggers. If that double-digit-TB fs is instead broken along functional/logical lines into say a dozen 1 TB each fs and that single block is corrupted, it can only be corrupted in one of them, so 11 of the dozen will be fine, and nuking to restore from backups just the single 1 TB filesystem of a dozen, instead of the single 12-TB fs, isn't such a big deal -- it remains realistically maintainable. Of course if at your scale 12 TB... or 12000 TB... is considered maintainable, great, but then we'd be unlikely to be having this discussion... -- Duncan - List replies preferred. No HTML msgs.
