I'm guessing the checksum was computed incorrectly and written twice, affecting both copies. I doubt it's a device problem. It might be useful to look through the archives specifically for checksum header error, it's kinda interesting Btrfs knows the problem is specifically there. What do you get for: btrfs-debut-tree -b 17478699876352 /dev/sdd2 I think the problem is isolated but you're probably best off to freshen up backups now while you can. Yes you can use restore to get data off the volume if you don't already have backups. And as for btrfs check --repair, only do that once you have backups and you're prepared to lose the file system. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
