Configuring disks

sgdisk --zap-all /dev/sdb
sgdisk -n 0:0:0 /dev/sdb
mkfs.ext4 /dev/sdb1

Single node cluster considerations

Reduce Longhorn replica count

For a single node cluster, set Longhorn's defaultClassReplicaCount to 1:

system/longhorn/values.yaml

longhorn:
  defaultSettings:
    nodeDownPodDeletionPolicy: delete-both-statefulset-and-deployment-pod
  persistence:
    defaultClassReplicaCount: 2
