Quick Tip - No space left on device when upgrading VCF Operations using VCF Operations Fleet Manager to VCF 9.0.2

01.22.2026 by William Lam // 3 Comments

Yesterday, I began upgrading my VMware Cloud Foundation (VCF) environment from version 9.0.1 to the latest 9.0.2 release. After successfully upgrading VCF Operations Fleet Manager, I then proceeded to upgrade VCF Operations, which includes running a pre-validation to ensure everything was okay before we can proceed.


As you can see from the screenshot above, I ran into the following error: "No space left on device" which was pretty vague, but I figured it had to do with my VCF Operations instance, since I was attempting to upgrade it ...

Improved Workaround for NSX Edge Deployment & Upgrade to VCF 9.0.2 running AMD Ryzen CPUs

01.20.2026 by William Lam // 7 Comments

If you are using an AMD Ryzen (Consumer) CPU for your VMware Cloud Foundation (VCF) lab environment, you have most likely have applied one of the required workarounds for either installing an NSX Edge (HERE) or upgrading an NSX Edge (HERE).

For those planning to install or upgrade to the latest VCF 9.0.2 patch release, which was just released today, you may come across this issue as shown in the screenshot below when attempting an NSX Edge upgrade.


While I have yet to run through the VCF 9.0.2 upgrade myself, a similar configuration file tweak from within the NSX Edge VM will be required. A colleague recently shared a more optimal trick for bypassing the non-supported AMD processor check, which would be simpler to implement for lab environments.

Disable HTTP Range Requests on Synology WebStation, Apache or Nginx

01.14.2026 by William Lam // 3 Comments

I use my Synology NAS to host a variety of services including a web server, file server and a backup system. As part of some testing that I had been performing with VMware Cloud Foundation (VCF) 9.1, I needed to ensure that my web server does not respond to HTTP Range Requests, which allow clients to retrieve specific byte ranges rather than downloading an entire resource in a single transfer.

We can check whether a web server supports HTTP Range Requests by specifying a range of bytes as demonstrated in this cURL example below:

curl -H "Range: bytes=0-10" -I http://depot.vcf.lab/PROD/vsan/hcl/lastupdatedtime.json -u $CREDS


You should receive an HTTP 206 response which indicates HTTP Range Requests is supported by your web server, which my Synology supports by default.

Unlike a traditional web server where disabling HTTP Range Requests is pretty straightforward, modifying the default behavior for Synology WebStation is slightly more complicated. After some trial and error, I was able to successfully disable HTTP Range Requests on my Synology system, and for those with a similar requirement, the following sections outline the steps for several popular web server backends.
