Hi Btrfs-List,

me and a friend have been using Btrfs on an Atom based home backup
server  (Arch Linux) for the past 1 1/2 years or so running on 2 1 TB
drives (with a few gigabyte of the first drive used for / so it's a
bit below 2 TB) and it has been running quite nicely.
However a few days ago while it was running a scan for new data from
some cloud based backup solution (who'd keep their only backup on
btrfs right :-)) it failed and all operations would fail with the
system not being able to reboot without hard shutdown.
So I installed a 3.3 Kernel and bootet into it.
Running btrfsck showed no errors and the filesystem was mountable again.
But then I got new errors albeit different ones. I only have logs of
the these new ones because the system was quite unstable with the
first one, so that's what is attached.
I can try to provide additional info if requested of course.

Greetings Niklas Schnelle
