Chapter 23. Configuring Persistent Volume Claim Protection
23.1. Overview Copiar o linkLink copiado para a área de transferência!
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.
