How to download offline copy of the Tanzu Kubernetes releases (TKr) Content Library?

by // 2 Comments

As part of the setup for vSphere with Tanzu, a local vSphere Content Library needs be created to store the various Tanzu Kubernetes releases (TKr) which users typically synchronize from VMware's online TKr Content Library repository.


I typically recommend configuring the content library subscription to only download files when needed, rather than the entire library, which is currently over 200GB+.

After standing up another vSphere with Tanzu environment, I needed to download additional TKr images but I could not reuse my existing subscribed content library since it was configured on a different vCenter Server.

With the ability to host a custom vSphere Content Library on my Synology, I realized a better solution would be for me to simply download the full VMware TKr Content Library and host that locally on my network rather than re-downloading the same images each time I have a new deployment.

Quick Tip - vSphere 7.0 Update 3o also supports disabling/enabling vSphere Cluster Services (vCLS) in vSphere UI

by // 2 Comments

I recently shared that in vSphere 8.0 Update, you can now easily manage the vSphere Cluster Services (vCLS) configuration by using either the vSphere UI or a new vSphere API, which simplifies this operation if you need to disable vCLS for a particular vSphere Cluster or if you need to remediate one by disabling and re-enabling the feature. Today, the process is less than ideal as you need to add a new vCenter Server Advanced Setting for each vSphere Cluster that you want to disable vCLS on.

For customers still on vSphere 7.x, I just found out from our vCLS Engineering team, that the latest vSphere 7.0 Update 3o, which was just released less than 24 hours ago, also includes this enhancement for managing vCLS configuration (enable/disable) using the vSphere UI!


One thing to note is that the new vSphere API that was introduced in vSphere 8.0 Update 2 to manage this exact same vCLS setting is not available in vSphere 7.0 Update 3o. If you wish to automate this configuration for vSphere 7.x environment, you will need to add the required vCenter Server Advanced Setting using the vSphere API.

Quick Tip - How to monitor when ESXi filesystem and partitions are filling up?

by // 3 Comments

Here is another tidbit on how you can leverage the power of vSphere Events, which now includes over 2K+ as of vSphere 8.0 Update 1 to help monitor when an ESXi filesystem and/or partition is low on disk space.

With vSphere 6.7 or later, we have two events that you can use to help alert when either an ESXi ramdisk (e.g. /var) or VFAT partition (e.g. bootbanks) has filled up.

  • Ramdisk: esx.problem.visorfs.ramdisk.full
  • VFAT: esx.problem.vfat.filesystem.full.other

When either of these occur, you can easily find them under the Monitor->Events section for an ESXi host as shown in the screenshot below.
