Designing Harvester with Longhorn: Architecture, Trust Boundaries, and Operational Safeguards
Learn how to size a Harvester cluster with Longhorn, define trust boundaries, monitor health, and handle failure modes to keep persistent volumes reliable.
kubernetesHarvester and Longhorn: Why Replication Factor Is Your First Storage Decision
Harvester uses Longhorn as its default storage engine to provide distributed block storage for VMs. The replication factor you choose drives durability, storage overhead and write latency, and the storage plane network determines whether that durability actually holds.
Using Harvester’s Longhorn Integration for Hyper‑Converged Infrastructure: A Practical Guide
Learn how Harvester’s Longhorn‑backed block storage makes hyper‑converged infrastructure resilient, the trade‑offs of synchronous replication, and a step‑by‑step example to create a replicated volume and recover a VM after node failure.
Architecting VM Persistence in Harvester: KubeVirt and Longhorn Integration
Harvester blends KubeVirt and Longhorn to give VMs the mobility of containers while preserving persistent storage. Learn how the architecture keeps VM data safe across node failures, how to verify the integration, and when to shift to external storage for low-latency workloads.
Taking Point‑in‑Time Snapshots of VMs in Harvester Without Downtime
Learn how to create point‑in‑time snapshots of running VMs in Harvester without downtime, verify them via CLI and Longhorn UI, and understand the storage trade‑offs involved.
Expanding Virtual Machine Disk Capacity in Harvester
Learn how to expand VM disk capacity in Harvester. This guide covers increasing volume size in the UI and performing the necessary partition and filesystem resizing within the guest OS.
