This is a "Damnit! I held the power button in and now it won't mount!" story, but I'm sharing what I found to learn what I can. And in case it's useful for btrfs development.
Also curious if my usage of Docker (an LXC thing, http://docker.io) has exacerbated things. I ask because it seems some btrfs mount options are breaking docker:
https://github.com/dotcloud/docker/issues/5429#issuecomment-42443919 - however, I'm not using space_cache or inode_cache myself.
Notes:
- I've taken a dd copy of the btrfs partition so that I can perform anything extra people would like to see.
- The following output is taken from the same machine, same partition layout but a fresh/working Debian testing install on a different disk. It should be reporting the same as it did before the corruption (it was definitely Linux 3.13).
- /dev/sda is a new disk, /dev/sdb3 is the corrupted btrfs partition.
- I have a single btrfs partition which contains the rootfs. I use subvolumes to separately snapshot /home, /vms, etc.
- mount options were: noatime,autodefrag,discard,compress=lzo

A timeline, starting around midday yesterday:
- I had some work to do and the VPN was slow, so on my laptop I upgraded docker from ~0.8.1 to 0.11.1.
- The upgrade stomped on my "-s btrfs" switch in /etc/default/docker which meant I was accidentally using docker with aufs for a while.
- I fixed this then purged all the containers and images (i.e. btrfs subvolumes).
- I did "docker pull debian:testing" which would have created a few new btrfs subvolumes.
- I ran some "docker build"s and at some point I had two builds going at once (two docker processes each creating btrfs subvolumes/snapshots at the same time).
- At some point one docker build was completed and the other was stalled trying to create a snapshot.
- Minutes later I noticed that my other applications were freezing up. The UI was still responsive and I could use the terminal.
- I looked at syslog and dmesg output in a terminal. There were no messages, ominous or otherwise coinciding with the disk i/o freezing up.
- I held in the power button.
- The reboot didn't boot. I ended up with the dreaded busybox shell, unable to mount btrfs rootfs...
- Removed disk and took a dd copy of sda3.
Other research...
Certain BTRFS mount options break docker -s btrfs:
- https://github.com/dotcloud/docker/issues/5429#issuecomment-42443919
The "AUFS on btrfs" thing has a few mentions in docker issues, perhaps it's nothing to do with btrfs though:
- https://github.com/dotcloud/docker/issues/829 - continued at...
- https://github.com/dotcloud/docker/issues/1075 - continued at...
- https://github.com/dotcloud/docker/issues/2961
- https://github.com/dotcloud/docker/issues/2056 # just another datapoint.

This shows that your trees are good except log tree, as if btrfs uses
backup trees for recovery it'll zero log tree and clear free space cache ,
I recommend you to use btrfs-zero-log.

> A timeline, starting around midday yesterday:
> - I had some work to do and the VPN was slow, so on my laptop I upgraded docker from ~0.8.1 to 0.11.1.
> - The upgrade stomped on my "-s btrfs" switch in /etc/default/docker which meant I was accidentally using docker with aufs for a while.
> - I fixed this then purged all the containers and images (i.e. btrfs subvolumes).
> - I did "docker pull debian:testing" which would have created a few new btrfs subvolumes.
> - I ran some "docker build"s and at some point I had two builds going at once (two docker processes each creating btrfs subvolumes/snapshots at the same time).
> - At some point one docker build was completed and the other was stalled trying to create a snapshot.
> - Minutes later I noticed that my other applications were freezing up. The UI was still responsive and I could use the terminal.
> - I looked at syslog and dmesg output in a terminal. There were no messages, ominous or otherwise coinciding with the disk i/o freezing up.
> - I held in the power button.
> - The reboot didn't boot. I ended up with the dreaded busybox shell, unable to mount btrfs rootfs...
> - Removed disk and took a dd copy of sda3.

> The "AUFS on btrfs" thing has a few mentions in docker issues, perhaps it's nothing to do with btrfs though:

Don't use the discard option on this kernel release. There are 2 know
bugs that made btrfs issue a discard on extents when it shouldn't,
which results in those messages you are seeing "btrfs bad tree block
start 0 xxxxxxxxxxx" (the key part is the 0 following the word start).
The fixes are:
1) https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=678886bdc6378c1cbd5072da2c5a3035000214e3
Happens both with -o discard and without it if you run fstrim
after the fs went into readonly mode. This is included in most stable
releases afaik, but certainly not in the kernel version you are using.
The btrfs-zero-log tool won't help here;
2) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=dcc82f4783ad91d4ab654f89f37ae9291cdc846a
Happens only with -o discard, and affects only the fsync log. You
can get your fs mountable again after using btrfs-zero-log (but losing
all data fsynced in the transaction that was open when a crash/reboot
happened). Not yet in any kernel release, only on linux-next at the
moment.

Thank you for trying btrfs, it's great for snapshots in docker, but
outside of the 2 helpful comments you already got, do yourself a favour
and use a newer kernel.
Btrfs moves fast, and 3.13 is way too old. The number of bugs (including
corruption bugs) that has been fixed since then is too long to list.
Try getting something newer than 3.16.2 at least, and if you're building
your own, 3.19.3 + this patch

(btrfs: simplify insert_orphan_item / 381cf6587f8a8a8e981bc0c1aaaa8859b51dc756 )
Cheers,
Marc
