Hi,
I think I experienced exactly the same issue, with Debian Wheezy, running
kernel 3.6 on an old fashioned spinning hd. I was using a 1GB raw image with
a plain ext2 filesystem running qemu-kvm with the cache=none option and I
got a lot of:
Dec 6 21:19:59 hephaistos kernel: [ 664.769629] btrfs csum failed ino
693974 off 470827008 csum 3711077113 private 141102393
I could still copy the first ~470MB of the raw image and save the only file,
that was important to me. Scrub was unable to fix it, but showed no further
errors.
Philipp
