How Kubernetes Persistent Volume Reclamation Causes Data Loss
from DevOps Daily with Fexingo: CI/CD, Kubernetes, and Modern Software Operations Hosted by Fexingo
In this episode of DevOps Daily, Lucas and Luna dig into a surprisingly common Kubernetes failure: the PersistentVolumeReclaimPolicy. When a PersistentVolumeClaim is deleted, the default 'Delete' policy can erase the underlying storage — and your data — before you realize what happened. Lucas walks through a real incident where a single accidental PVC deletion nuked three production databases because the reclaim policy was set to 'Delete' instead of 'Retain'. They break down how PersistentVolumes and Claims actually interact, why the default policy is so dangerous for stateful workloads, and how you can protect yourself with namespaces, RBAC, and backup strategies. Plus, they share why StorageClass reclaim policies often override your PV settings, and how a simple pre-delete hook or manual PV retention can save your team from a nightmare. Tune in for a practical guide to making sure your persistent data survives deletions. #Kubernetes #DevOps #PersistentVolume #DataLoss #StorageClass #ReclaimPolicy #StatefulSets #Backup #RBAC #CloudNative #Technology #DevOpsDaily #FexingoBusiness #BusinessPodcast #K8s #Infrastructure #IncidentResponse #Storage Keep every episode free: buymeacoffee.com/fexingo
