Was it RAID5/6? If not that's worrying. I've had one BTRFS system eat itself to the point that it could only be mounted read-only, but no data loss.

Not the OP, but I deployed btrfs on tens of embedded systems that had their power consistently cut on a daily basis. Ended up with unmountable filesystems repeatedly. Switched to ext4 and never had an unmountable filesystem again.

These were single disk systems, no raid at all.
