Longhorn Storage
See: Longhorn Docs v 1.8.1
Installation Notes
Important Settings
- Number of Replicas: Set to 1 (default is 3) to accommodate smaller clusters
- This avoids "degraded" volumes when fewer than 3 nodes are available
- For production with 3+ nodes, consider changing back to 3 for better availability
Common Operations
- View volumes:
kubectl get volumes.longhorn.io -n longhorn-system
- Check volume status:
kubectl describe volumes.longhorn.io <volume-name> -n longhorn-system
- Access Longhorn UI: Set up port-forwarding with
kubectl -n longhorn-system port-forward service/longhorn-frontend 8080:80
