BTRFS now has scrub support for RAID5/6

Finally thanks to this this patch in 3.15RC2 BTRFS is able to scrub Raid5/6 data correctly. It doesn't actually scrub the parity blocks yet but before that patch it wasn't actually scrubbing any of the data stored in Raid5/6. This is great news because I am redoing my server shortly and am seriously considering switching to Raid5 for my data backup that is currently stored in two mirrored 500 GB drives. I plan on getting rid of the 500 GB drives and replacing the whole system with three 3TB drives in BTRFS Raid5. This should give me 6TB of usable space and protect my data against a single drive failing.
