I'd still start with just check, because there are some targeted repair options that are considered safer.

 

I don't know what is giving you the device busy.  Did you do a sync before umounting?

 

You could try doing a btrfs device scan first. If all else fails you could boot up in tech support mode, as that won't mount the data volume.  Let me know if you need to try that.
