I would really like md arrays to be treated read-only when first assembled and not written to at all until either: 1/ a write request is received or 2/ a bad/missing drive is detected and a spare is present. This could be achieved (I believe) with complete backwards compatability but, of course, it requires some work and testing. To address your problem of the assembly phase finding all but on of the drives and going ahead anyway, you could use 'mdadm --assemble' without --run or --scan. Then it will only assemble if all drives are present: mdadm --assemble /dev/md1 --super-minor=1 /dev/sd* should do it.
