Deploying Resilient Block Storage on K3s Clusters with Longhorn

Lightweight Kubernetes (K3s) has emerged as the standard for edge computing and private infrastructure. However, stateful workloads require resilient distributed storage that avoids single-point-of-failure bottlenecks.

Storage Architecture Blueprint

Longhorn coordinates microservices-based block storage across worker nodes, ensuring high availability even during abrupt node failures.

# Verify volume replicas across worker nodes
kubectl get volumes.longhorn.io -n longhorn-system

By strictly forbidding block storage daemonsets on master control-plane nodes, we maintain cluster stability and eliminate resource contention.
