The forthcoming[1] btrfsck tool should handle that particular error, I believe.

I noticed a similar problem was discussed here, with a solution:

http://www.spinics.net/lists/linux-btrfs/msg07572.html

where a "btrfs-selects-super" was used:

Quoted 6 lines

git clone
git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs-unstable.git
next
(or git pull into your existing checkout)

Quoted 7 lines

Then
make btrfs-select-super
./btrfs-selects-super -s 1 /dev/xxx
After this you'll want to do a full backup and make sure things are working properly.

However, I don't see the tool when I clone the latest git - am I missing something?

FYI, "btrfsck -s 1 /dev/vda3" says:

The forthcoming[1] btrfsck tool should handle that particular error, I believe.
I noticed a similar problem was discussed here, with a solution:
http://www.spinics.net/lists/linux-btrfs/msg07572.html
where a "btrfs-selects-super" was used:
Quoted 8 lines
git clone
git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs-unstable.git
next
(or git pull into your existing checkout)
Then

Quoted 8 lines

Quoted 5 lines
make btrfs-select-super
./btrfs-selects-super -s 1 /dev/xxx
After this you'll want to do a full backup and make sure things are working properly.
However, I don't see the tool when I clone the latest git - am I missing something?

It's not built by the makefile by default; "make btrfs-select-super" as stated above will make it.

You checked out the master branch into a folder called next. "-b next" is the option to checkout a specific branch. From your existing checkout, "git checkout -t origin/next" will switch to that branch. --

Good catch - thanks for a hint.

The filesystem mounted and was usable.
