===Partitioning the drives===
Now need to create the partition for the drives using parted.

Remember to set the Max size to whatever size hard disk drives you are using, and change the device sdX value for each drive in the chain.
Remember to set the max size (4.00TB above) to whatever size hard disk drives you are using also you will need tochange the device sdX value for each drive in the chain.
===Creating the array===
Check which ''md'' numbers are in use by running the command ''cat /proc/mdstat'' increment one number highest number so in my case I am using md3.
mdadm --create /dev/md3 --level=raid5 --raid-devices=6 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/hda1 /dev/hdb1
*Be Advised this command will process quickly but in the background it will be conducted a re-sync of the RAID array you can monitor this by running cat /proc/mdstat.
It highly advisable to wait for the re-sync to be completed before proceeding.
