===Creating the array===
===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.
Check which ''md'' numbers are in use by running the command ''cat /proc/mdstat'' select the highest number md number and add one we will us md3.
mdadm --create /dev/md3 --level=raid5 --raid-devices=6 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/hda1 /dev/hdb1
mdadm --create /dev/md3 --level=raid5 --raid-devices=6 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/hda1 /dev/hdb1
Change the md3 number to the one you have selected, you will also need to change the number of raid devices and list each of the devices to use in the array.
*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.
