What problem does it solve?
This Skill prevents Longhorn from wasting replicas on tiny eMMC disks and causing DiskPressure, pod evictions, and storage-related outages in mixed-disk Kubernetes clusters.
Core Features & Use Cases
- NVMe-First Storage Design: Guides Longhorn to place replicas on NVMe-backed disks instead of the default eMMC path.
- StorageClass and Node Policy Tuning: Helps configure disk selectors, node annotations, and default disk settings so scheduling stays predictable.
- DiskPressure Recovery: Supports emergency remediation when replicas are already trapped on eMMC and nodes need eviction or rescheduling.
- Use Case: An RK1 node hosting OpenClaw or NPU workloads starts filling its root disk; this Skill helps move storage to NVMe before Kubernetes begins evicting critical pods.
Quick Start
Use the longhorn skill to review the cluster’s disk layout, verify NVMe-only replica placement, and recommend the Longhorn and StorageClass changes needed to prevent DiskPressure.
