⏱️TIMESTAMPS⏱️
0:00 – Intro
0:46 – What we will be covering
2:20 – creating SD card
2:43 – enable ssh on boot
3:04 – enable usb ports on IO card
3:26 – initial boot of CM4
4:10 – install OS updates
5:20 – checking USB ports being active
5:53 – install mdadm for raid
6:04 – checking mdadm
6:17 – checking USB drives
6:57 – partitioning drives
7:57 – checking partitions
8:58 – setting up raid 0
9:40 – setting up raid 1
10:33 – checking array build status

sudo apt-get update
sudo apt-get upgrade -y

Create zero bytes file named ssh in root of boot sd

Check for devices plugged in on usb
lsusb -t

Sudo nano /boot/config.txt
Add this line – dtoverlay=dwc2,dr_mode=host

Save and exit
Reboot pi and usb should be active

!! Install mdadm
sudo apt-get update
sudo apt-get upgrade -y
sudo apt-get install mdadm -y

! Verifies mdadm is installed
sudo mdadm -V

!verify raid setup
sudo mdadm –examine /dev/sda /dev/sdb

! Show status of array building
cat /proc/mdstat

! For more detail in array building process
sudo mdadm –detail /dev/md0

! To stop array
sudo mdadm –stop –scan

! List drives current attached
lsblk -o NAME,SIZE,FSTYPE,TYPE,MOUNTPOINT

1. Identify mount point
lsblk -o NAME,SIZE,FSTYPE,TYPE,MOUNTPOINT

2. Raid 0
sudo mdadm –create –verbose /dev/md0 –level=0 –raid-devices=2 /dev/sda /dev/sdb

3. Raid 1
sudo mdadm –create –verbose /dev/md0 –level=1 –raid-devices=2 /dev/sda /dev/sdb

4. Create mount point
sudomkdir-p /mnt/md0

5. Save array layout
sudo mdadm –detail –scan |sudotee-a /etc/mdadm/mdadm.conf

6. Automounting at boot
echo’/dev/md0 /mnt/md0 ext4 defaults,nofail,discard 0 0’|sudotee-a /etc/fstab

Build a Raspberry Pi RAID NAS Server – [UPDATED 2020]

Good way to introduce compute module 4

Raid 0 – striping data across drives
• Lowest overhead in write speed
• Single Drive failure results in total data loss
Raid 1 – mirrored drives (50% overhead)
• Match set of drives
• Single drive failure tolerated
• Slow write performance
• Data is written to both drives
