The Volume That Wouldn't Let Go: A Kubernetes PVC War Story

Short summary

A production service failed when a Kubernetes PVC remained attached to an unreachable node. The author explains why Kubernetes conservatively waits ~6 minutes before force-detaching (preventing data corruption) and shows how to resolve it by confirming the node is truly down and deleting its object. A practitioner's guide to understanding Kubernetes' safety-first design in incident response.

• •Multi-Attach PVC errors occur when volumes stick to unreachable nodes that still might be writing data
• •Kubernetes waits ~6 minutes before force-detaching to prevent filesystem corruption from dual writers
• •Resolution: verify node is actually dead (cloud console), then kubectl delete node to allow reattachment
