Adding the drive to the Raid

*<blockquote> mdadm --add /dev/md# /dev/sd# (# is the number of the drive you adding)

Growing The Raid

*<blockquote> mdadm --grow --raid-devices=# /dev/md$ (# is the total number of the drives in the array and $ is the raid array )

Now we let the Raid array rebuild and we can watch it reshape by Typing

*<blockquote> watch cat /proc/mdstat

It will take a couple hours for the drive to reshape (PLEASE do not reboot the machine during the reshaping process)

After the reshape finished successfully we need to make sure that the mdadm.conf has the correct drive number in it.

*<blockquote> nano /etc/mdadm.conf

Here we change the number of total drives you have in your array
