We have run btrfs in RAID configuration, but that has usability issues, even just doing RAID-1. We've switched back to using MD (mdadm) for RAID-1 setup, and then using btrfs on top of that for the snapshots, send / receive, block-level CRC and such. Dealing with failed drives isn't as easy with btrfs as it is with Linux MD.
