I'm out of ideas how this could normally happen. For a single device the filesystem size accounted by superblock and by sum of all block groups should the same given that no devices are added/removed. david -- 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
