Try booting with bootflags=ro,recovery in grub (with the latest possible kernel), or mounting with -o recovery from the livecd (likewise). If it works, then you're done, you should be able to boot normally after a clean umount and shutdown. If it doesn't, post dmesg from the attempt. > I'v been told this is missing relevant details. > The original kernel version was 3.2.0-something (standard Ubuntu 12.04 LTS). > I've since upgraded to 3.7 but this has made no difference. > Right now I don't have the dmesg, I'll post it later. > > Currently I've been able to mount the partition with btrfs-restore and am > trying to rsync it on another ext4 volume. Terminology note: btrfs-restore doesn't "mount" anything, it just copies files directly from a device. -- 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
