That is just wrong. My understanding is that the wants to add wd3 later
as another part of the raid1.

This is what i did with adding two 3TB disks:

---------------------------------------------------------
# Add wedge to wd0
gpt create wd0
gpt add -b 64 -s 5851054080 -t raid wd0
dkctl wd0 addwedge Disk_1 64 5851054080 raidframe

# Configure the raid
raidctl -v -C /root/raid0.conf raid0

# Set the serial number
raidctl -v -I $timstamp raid0

# Initialize the raid
raidctl -v -i raid0

# Check initialize
raidctl -v -s raid0

# Add a wedge to raid0
gpt create raid0
gpt add -b 128 raid0
dkctl raid0 addwedge Raid0 128 5851053855 ffs

# Create the file system on the raid
newfs -O 2 -b 32k -f 4k -i 256k /dev/rdk1

# Mount it
mount /dev/dk1 /mnt

# Reboot

# Configure the raid again
raidctl -v -C /root/raid0.conf raid0

# Add wedge to wd1
gpt create wd1
gpt add -b 64 -s 5851054080 -t raid wd1
dkctl wd3 addwedge Disk_2 64 5851054080 raidframe

raidctl -a /dev/dk1 raid0
raidctl -F component1 raid0

# Set auto config
raidctl -v -A yes raid0

# Mount it
mount /dev/dk2 /mnt
---------------------------------------------------------

The only issue is that I have to use dk2 and not the id of the wedge
for mounting :(
