Since btrfs doesn't support badblocks, this btrfs mailing list post[1] suggested to use mdadm RAID0 3.1+. Is there a way of having blocks from a spare device automatically replacing bad blocks when they are next written to (like SMART does for HDDs)? Or would mdadm be able to add a "badblocks layer" to btrfs in some other way? My use case is mining storj - I don't mind some data loss.
