No problem. Since the Arch repo's version of f2fs-tools does not include
fsck.f2fs, I built it from your git repo
(git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs-tools.git)
using an Arch Linux install usb on the same machine, with Linux
3.9.8-1 .
The output on the main system partition is:

I also ran fsck.f2fs on these partitions with higher debug levels, but
the output files are somewhat large, so I won't bother sending those
unless you need them.
Thanks,

Hi,
Thank you for the report.
If possible, could you run fsck.f2fs to the failed device?
Otherwise, can you send the disk image to me?
Thanks,
