my problem is that I have a bunch of crappy disks which seem unable to reliably remap bad areas after a read error.
IME, discs don't remap after read errors, only on writes.
This obviously makes the read error rewrite feature of our beloved RAID5/6 code somewhat less than useful.
Are you sure that refresh-writes triggered by read errors are expected behaviour of md's RAID5/6 mode? Only they weren't for RAID1 until somewhat recently (2.6.15, IIRC).
