 Alteeve Wiki :: How To :: Create an mdadm RAID array

This coverts creating a software RAID array in EL8.

This will combine /dev/nvme0n1p4 + /dev/nvme1n1p4 and /dev/nvme2n1p4 into a new /dev/md1 RAID 5 array. 

mdadm --create /dev/md1 --raid-devices=3 --level=5 --spare-devices=0 /dev/nvme[012]n1p4
