After dd_rescuing a device that belongs to a degraded raid-5 array I got a summary like this: Summary for /dev/sdb1 -> /dev/sdg1: dd_rescue: (info): ipos: 976760001.0k, opos: 976760001.0k, xferd: 976760001.0k, errs: 48, errxfer: 24.0k, succxfer: 976759977.0k Since it's a degraded array I'm guessing there is gonna be 24 KiB worth of damage to the filesystem. But I do have fairly recent full filesystem level backups, it would be nice if I could figure out what those 48 bad sectors contained, so I could restore just those things from my backups. So basically I would need to figure out which blocks are the 48 damaged ones on /dev/md0 and then ask my filesystems debugging tools to tell me what those blocks should contain. And to make it a bit more fun there is a luks crypto layer between the md and filesystem, but that should be a simple luks header sized offset. -- 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
