There's a worthwhile distinction between stability of raid56 vs all other profiles, and btrfs multiple device failure behavior. Right now there's no monitoring or notification of failures to user space. In fact Btrfs itself doesn't really understand device failures, a device can spit out many read or write errors and Btrfs keeps trying to read and write. So there's no equivalent to faultiness like with md/mdadm. Therefore you'll have to figure out a way to monitor kernel messages, maybe via a script that parses for btrfs messages and emails any such messages ever 10m or whatever.
