The device will come up with an increased number of raid-disks and with the final device marked as failed. If you now raidhotadd the new disk to the array, reconstruction will start and the new disk will be synchronized to the existing data. This assumes we're talking about a raid1 array - you can't use the procedure to increase the number of disks in a raid5 or raid0 array without loosing your data.
