Btrfs was making two copies of metadata blocks and restored corrupted copies from good ones, and also signaled me that user files were also affected (via data checksums). FS checksums do work, and if you have redundancy for the corrupted part (such as metadata DUP by default, or data DUP (unusual) or data RAID1), allow the FS to sustain through corruptions, including hardware-caused ones. -- With respect, Roman -- 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
