Hello all.
My system failed and I thought of trying btrfs.
After repartitioning and installing, nothing booted and my (btrfs
formatted) home partition is unmountable (parent transid).
I discovered I can mount the partition with btrfs-restore but, since I'm
running off of a live usb Ubuntu, mounting fails at some point due to
lack of space.
So is there a way I can mount the partition on a live distro to recover
what is recoverable?
Thank you
Claudio

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.

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.

Terminology note: btrfs-restore doesn't "mount" anything, it just
copies files directly from a device.

Already tried mounting with -o recovery to no avail.

I didn't know that at the time of writing.
