The third disk that you added became a hot spare.
You cannot add an extra active drive to a RAID array without using
mkraid.
In you case, you could edit /etc/raidtab to list the third strive as a
"failed-disk" instead of a "raid-disk", and set the "nr-taid-disks" to
3.
Then run mkraid. It shouldn't destroy any data, but the raid system
should automatically start building data onto the new drive.
