You can always do a super-rebuild. Simply, backup the contents of your drive to another computer or external drive.
Then start from scratch with your softraid 1 array, which will just be re-created, and take < ~1 min. Then copy the data back. Given this kind of setup, you can probably be back up and running in a matter of hours rather than a matter of days.
