Create A Basic RAID1 Array on Linux
How to create a basic RAID 1 array on Linux. We use Linux Mint 21.3 to create a 1 TB mirrored array using the command line.
Commands/Steps used in this video:
1) Open terminal
2) List block devices
lsblk
3) Choose devices for array
/dev/sdb and dev/sdc
4) Check RAID status
cat /proc/mdstat
5) Create Array
mdadm --create --verbose /dev/md1 --level=1 --raid-devices=2 /dev/sdb /dev/sdc
6) Check RAID status
cat /proc/mdstat
7) Create a filesystem
mkfs.ext4 /dev/md1
8) Create a mount point
mkdir -p /mnt/md1
9) Mount the drive
mount /dev/md1 /mnt/md1
10) Check if mounted
df -h -x tmpfs
11) Save array layout
mdadm --detail --scan | sudo tee -a /etc/mdadm/mdadm.conf
12) Check if saved
cat /ect/mdadm/mdadm.conf
13) Update the initramfs, or initial RAM file system
update-initramfs -u
14) Add the new filesystem mount option to the /etc/fstab file for automatic mounting at boot:
echo '/dev/md1 /mnt/md1 ext4 defaults,nofail,discard 0 0' | sudo tee -a /etc/fstab
15) Find UUID
blkid
16) Change fstab to UUID
nano /etc/fstab
