In theory, yes, but in practice, they don't -- or do they? I thought that even if you use RAID 6, md doesn't check all members on each read request, calculate parities, and mask silent platter-level corruption by ignoring a member spewing bad bits. It just uses parities to fill in missing data if a member fails. Or does it actually do error detection, and I'm confused? -- Robert L Mathews, Tiger Technologies, http://www.tigertech.net/ -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
