Quick Tip: How to Identify Which Kubernetes Cluster Owns a vSphere Container Volume (PV)

by // Leave a Comment

I was recently cleaning up some orphaned vSphere Container Volumes and while I was able to compare the Persistent Volumes (PV) IDs against the ones currently in use by a couple of Kubernetes clusters, I wanted to be 100% sure before removing them, especially since I planned bulk delete using PowerCLI’s Remove-CnsVolume cmdlet.

You can view all provisioned vSphere Container Volumes in the vSphere UI by navigating to vSphere Cluster->Monitor->Cloud Native Storage->Container Volumes. In addition to the volume details, you also get access to all of the associated metadata and labels, very similar to what you would see using kubectl, which is quite nice!


While reviewing the PV IDs in the UI, I noticed an attribute named Kubernetes Cluster, which appeared to identify the Kubernetes (K8s) cluster that owned the volume. How do I find this Kubernetes Cluster ID?

VCF 9.1 - OCuLink External Graphics (eGPU) Passthrough with vSphere Kubernetes Service (VKS)

by // Leave a Comment

The Minisforum MS-A2 continues to be a popular and versatile platform for running VMware Cloud Foundation (VCF) 9.1 in a lab environment. While the MS-A2 may be small in size, it is surprisingly capable and can even be configured to support an NVIDIA RTX 4000 Ada (20GB VRAM) GPU, which I had used to deploy VMware Private AI Services (PAIS).

Although there are several half-height GPUs that can fit in an MS-A2, the overall selection remains relatively limited. For users looking for additional GPU flexibility, the MS-A2 supports an OCuLink half-height PCIe card, enabling the use of a much broader range of discrete GPUs.


Thanks to a fellow colleague who recently shared their success with me using this setup on VMware Cloud Foundation (VCF) 9.1, including GPU passthrough to vSphere Kubernetes Service (VKS) cluster for AI experimentation, below are the specific BOM details for those interested.

VCF 9.1 - Unable to fetch plugin metadata for VCF Consumption CLI

by // Leave a Comment

I recently came across an issue while syncing the VCF Consumption CLI plugins, it would always show the following attempting to fetch 9.0.1 plugin even though my VMware Cloud Foundation (VCF environment was already at 9.1.

> vcf plugin sync

[i] The vcf cli essential plugins have not been installed and are being installed now. The install may take a few seconds.
[i] Installing plugins from plugin group 'vmware-vcfcli/essentials:v9.0.1'
[x] Failed to install plugin 'telemetry:v9.0.1'
[!] unable to install plugin 'telemetry': unable to fetch the plugin metadata for plugin "telemetry": unable fetch plugin binary: Collecting images: GET https://projects.packages.broadcom.com/v2/vcf/vcf-cli-plugins/ga/vmware/vcfcli/darwin/amd64/telemetry/manifests/v9.0.1: MANIFEST_UNKNOWN: The named manifest is not known to the registry.; map[manifest:vcf/vcf-cli-plugins/ga/vmware/vcfcli/darwin/amd64/telemetry]

[!] No active contexts available to perform plugin sync

After reaching out to Engineering, I came to learn that the behavior of the VCF Consumption CLI in 9.1 has changed and no longer pulls from the Broadcom public repository. Users can either download the VCF Consumption Plugins and relocate the OCI images into their own container registry or for an air-gapped environment, the plugins can also be installed locally.

I opted for second option for simplicity sake even though I do have Harbor Container Registry running.
