Re: How does btrfs handle bad blocks in raid1?

I really suspect a lot of bad block issues can be avoided by monitoring SMART data. SMART is working very well for me with btrfs formatted drives. SMART will detect when sectors silently fail and as those failures accumulate, SMART will warn in an obvious way that the drive in question is at end of life. So I think the whole bad block issue should ideally be handled at a lower level than filesystem with modern hard drives.
