This isn't raid5... when you put the new drive in raid1 and raidhotadd
(new drive, putting in the same old one would be a bad idea unless you
think the old drive is still good) the resync algorithm is a simple copy.
In the raid5 case you're right, you have to have at least two data
sources to XOR and generate the resync.
