Thanks for all the info guys.
I ran some tests on the latest 3.12.8 kernel. I set up 3 1GB files and
attached them to /dev/loop{1..3} and created a BTRFS RAID 5

I ran some tests on the latest 3.12.8 kernel. I set up 3 1GB files and attached

I copied some data (from dev/urandom) into two test files and got their MD5
sums and saved them to a text file.

Would it be reasonably accurate to say btrfs' RAID5 implementation is

if a device failure goes horribly wrong, then?
This is a reasonably serious question.

Thanks again for the added info; very helpful.
I want to keep playing around with BTRFSS RAID 5 and testing with it...

There are different values of testing and of production - in my
world, at least, they're not atomically defined categories. =)

From the wiki, I see that scrubbing is not supported on a RAID 5 volume.
Can I still run the scrub routing (maybe read-only?) to check for any
issues. I understand at this point running 3.12 kernel there are no
