Frequent Query container volume async Tasks in vSphere UI 

by // Leave a Comment

If you are running vSphere workloads that leverage Cloud Native Storage (CNS), whether through upstream or third party Kubernetes, vSphere Kubernetes Service (VKS), vSAN File Services, or VCF Automation (VCFA), you have likely noticed recurring "Query container volume async" tasks appearing in the vCenter Recent Tasks pane.


I have generally treated these as informational events and ignored them, but during a recent VCFA upgrade I had noticed an uptick in the frequency of these tasks and wanted to understand where they were coming from and whether I could reduce the frequency of these events.

Quick Tip - Debugging "stuck" vSphere Supervisor being removed

by // 1 Comment

Disabling or deactivating vSphere Supervisor can take some time depending on the number of resources you may have deployed, which all need to be properly cleaned up.


In case the removal is taking longer than expected, there is not much information provided to the user in the vSphere UI.

However, I recently learned about a useful way to understand what is actually happening on the backend by looking at the vSphere Supervisor service logs, especially if you believe the operation is "stuck", which ended up being my situation.

Automating the Retrieval of VCF Installer Deployment Milestones

by // Leave a Comment

When deploying a new VMware Cloud Foundation (VCF) instance, whether converting an existing vSphere based environment or deploying a net new setup, the VCF Installer provides a graphical view of the current milestones and the individual tasks within each milestone.


While you likely will not sit and watch the progress of each step, you may want to retrieve the the progress programmatically, which can be accomplished by using the VCF Installer API.

Similar to the VCF Installer UI, we can also retrieve the individual milestones and get some additional useful information such as the start and end time for a given milestone. This can be handy if you want to understand how long each milestone is taking, which is not a view you can quickly find in the UI. To understand the duration for a given milestone with the UI, you need to look at the first and last task to understand the milestone duration.
