Well, if you've already installed the first hard disk, then i guess u'll have to shrink it for the raid partition. Ideally, it should be done at install time even. It'll only help if the raid partitions are on

Can he not umount the partitions, create the raid arrays by including the second disk, and mount the arrays again?
Sadly Not. Notice, he mentions software raid, which needs to be a separate physical partition type. and even many hardware raid controllers will wipe the contents while initialising an array. You can only swap disks without data loss after the raid 1 array is running.
