I'm playing with mkfs.btrfs -m raid1 -d raid1. I put som data there
and now I write random data on one of physical disks directly.
Filesystem and file contents looks fine but I cannot see any errors,
is there any way to see that one disk from raid1 is failing?
Thanks

I have unmounted and again mounted btrfs filesystem, now I can see
errors in dmesg.
Is there also some error/health summary, like in btrfs fi show?

There is no error accounting or reparing yet, but you can check out the
scrub patches. They'll read and repair (if there's a second copy
available) all on-disk data. You can pull it here:
git://git.kernel.org/pub/scm/linux/kernel/git/arne/btrfs-unstable-arne.git
scrub
and
git://git.kernel.org/pub/scm/linux/kernel/git/arne/btrfs-progs-unstable-arne.git
scrub
