btrfs crashes

Hi everybody,

we are using a btrfs RAID 1 with four 2TB hard drives on a Debian 7.1 
(Kernel 3.9.6).

After about one year of working, there was an error in messages log and 
the filesystem was mounted read-only.

After that I restarted the system but that doesn''t fix the bug. The 
btrfs-filesystem couldn''t be mounted.

I attach four logs:

-> when the error occured
-> after the error occured
-> when rebooting the system
-> when I tried ti mount manually

Before I rebuilt the filesystem (formatting everything and creating a 
new btrfs-pool) I made a btrfs-image. I can provide it to you.



messages when the error occured:

Can you file a bugzilla at bugzilla.kernel.org (make sure the component is set
to btrfs) with all of this information and a link to the image, and the output
of btrfsck?  Please use the most recent version of btrfs-progs

git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git

Thanks,

Josef
