Configure a RAID 5

• List existing disk

fdisk -l

• Get info about existing RAID

cat /proc/mdstat

• Get more info about a specific RAID

mdadm --detail /dev/md0

• Improve the speed of RAID creation

sysctl -w dev.raid.speed_limit_max=1000000

• Create the RAID with 4 disks:

mdadm --create /dev/md0 --level=5 --raid-devices=4 /dev/sda /dev/sdb /dev/sdc /dev/sdd

• Format the RAID volume as a partition

mkfs.ext4 /dev/md0

• Mount the RAID volume as a partition

mount /dev/md0 /mnt

• To ensure that the RAID configuration is saved and can be reassembled at boot, save the configuration:

mdadm --detail --scan | sudo tee -a /etc/mdadm/mdadm.conf

!> Important /!\ Verifiy the /etc/mdadm/mdadm.conf file that the config does not contains duplicate /!\

• Update the initial RAM filesystem so that the RAID array is recognized at boot:

update-initramfs -u
