Set up persistent storage for K3s (via USB drive)

  1. Get root: ssh pi-k3s-master.local -t sudo su
  2. Find your disk via fdisk -l (e.g. /dev/sda1)
  3. Erase drive by repartitioning: mkfs.ext4 /dev/sda1
  4. Mount drive: 
    mkdir /mnt/pi-k3s-storage
chown -R ericboehs:ericboehs /mnt/pi-k3s-storage
mount /dev/sda1 /mnt/pi-k3s-storage
  5. Configure auto-mount: 
    echo "UUID=$(blkid -s UUID -o value /dev/sda1) /mnt/pi-k3s-storage ext4 defaults 0 0" >> /etc/fstab
  6. Install nfs server on master: 
    apt-get install -y nfs-kernel-server
echo "/mnt/pi-k3s-storage *(rw,no_root_squash,insecure,async,no_subtree_check,anonuid=1000,anongid=1000)" >> /etc/exports
exportfs -ra # Start nfs
  7. Install nfs client on nodes: 
    ssh pi-k3s-node1.local -t "sudo su"
mkdir /mnt/pi-k3s-storage
chown -R ericboehs:ericboehs /mnt/pi-k3s-storage
mount 10.0.1.90:/mnt/pi-k3s-storage /mnt/pi-k3s-storage
echo "10.0.1.90:/mnt/pi-k3s-storage /mnt/pi-k3s-storage nfs rw 0 0" >> /etc/fstab
reboot
df -h /mnt/pi-k3s-storage
