I don't know what it means. Maybe Qu has some idea. He might want a btrfs-image of this file system to see if it's a bug. There are still some bugs found with lowmem mode, so these could be bogus messages. But the file system clearly has problems, the question is why does such a new file system have these kinds of problems that can't be fixed by normal repair because they aren't even being detected; or maybe there is no problem on disk per se, the problem might be a bug. In which case, off chance going back to a substantially older kernel might help. Maybe the latest 4.9 series kernel? -- 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
