vCenter Task Console shows repetitive updateVStorageObjectMetadataEx.label tasks due to orphaned container volume object

Products

• VMware vSphere Kubernetes Service

Issue/Introduction

vCenter Server exhibits a high frequency of vslm.vcenter.VStorageObjectManager.updateVStorageObjectMetadataEx.label tasks (e.g., every 20 seconds).
While tasks show as completed, the constant refresh can impact UI performance and log clarity.

Environment

VMware vCenter Server 8.x

Cause

A partially deleted Kubernetes namespace contains Persistent Volume Claims (PVCs) whose backing First Class Disks (FCDs/VMDKs) or snapshots are missing or inaccessible. The Cloud Native Storage (CNS) service continuously attempts to update metadata for these objects, triggered by pod restart loops on disabled nodes.

Resolution

1. Review vsanvcmgmtd.log to identify the specific namespace and PVC triggering the updates.
2. Confirm if the namespace is orphaned or intended for deletion.
3. Delete the problematic namespace using kubectl delete namespace <name>.
4. Verify that the repetitive tasks stop in the vCenter Task Console.
