PowerProtect Data Manager 19.15 Kubernetes User Guide

PowerProtect Data Manager waits for up to 60 seconds for the temporary persistent volume/persistent volume claim (PVC) it creates to be removed from the cluster. If the storage or CSI driver is under heavy load and unable to delete the temporary PV/PVC before the timeout period expires, PowerProtect Data Manager backups of non-vSphere CSI storage classes complete with a warning message similar to the following, even when the PV/PVC is subsequently removed by the CSI driver:

PV <PV name> of snapshot <snapshot name> might not be deleted. Context deadline exceeded.

If this issue continues to occur, contact the storage vendor.
