Scheduling a (weekly) complete media scan where all surfaces of all drives
get read; in case of read errors a repair is tried: the content for the
failed sector is reconstructed just as if the drive had completely failed and
rewritten to the failed sector; if reading works afterwards, regard the
repair as successfull and continue using the drive.
This can't currently be done.

I'd suggest to start from the resync code and instead use it to check
instead; add an ioctl to trigger the consistency scan, then you can
schedule it via cron all you like.
