Chapter 23. Configuring Persistent Volume Claim Protection
23.1. Overview Copiar enlaceEnlace copiado en el portapapeles!
OpenShift Container Platform can be configured to have the persistent volume claim (PVC) protection feature enabled. This feature ensures that PVCs in active use by a pod are not removed from the system, as this may result in data loss.
PVC protection is an alpha feature and may change in a future release of OpenShift Container Platform.
