No need to remove the bitmap.
But be very careful that the disk is exactly the same size (or bigger).
I recently had a disk that was slightly smaller then advertised !

But if it's a raid6 why not just jank a disk ?
It's still going to be redundant, but only on 1 disk.

I think it would not be accepted by MD if the size was smaller than needed. At least with --replace. With the dd thing I don't know: it might trust the metadata and bypass the check.... I'd be careful in that case indeed.
