After reading data, when checksum shows it's corrupted, another copy (hopefully correct) is read from other disk location. This is adding security by the price of half storage capacity. Which seems like a fair game, given todays 1,5TB HDDs. -- Tomasz Torcz -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
