If there's a missing device, 'btrfs dev del missing' should work. But there's no device missing for 'dev del' it's only missing for 'dev ready' which makes no sense. I suggest filing a bug, bugzilla.kernel.org. Something like 'bogus 'some devices missing' prevents boot. And then give examples in the summary: - mounts OK without degraded - btrfs check does not report missing devices - btrfs fi show does not report missing devices - btrfs fi show -d does report missing devices - btrfs dev del missing reports there are no missing devices - btrfs dev ready exit value 1, so boot always fails I don't know what debug info is useful for this case either. Maybe btrfs-image, btrfs-debug-tree output to a file maybe the chunk tree has a clue about this phantom missing device. And then once you file the bug, and post the URL here, go on the IRC channel tomorrow (business hours U.S. time) and reference it and ask what other information devs would want before you blow away the volume and start over. Because presumably you need to get back to work, and to do that at this point, baring a dev having an idea how to fix it, you'll need to blow it away. Make a backup while you can in the meantime. -- Chris Murphy -- 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
