Upgrade to vCenter Server 7.0U2 fails at stage 2: “The source disk ‘/’ is too small to fit the export requirements”

Today a short post on a VMware Knowledge Base article that was published recently. It’s about a failure to upgrade your vCenter Server to 7.0 update 2. The upgrade fails with the message: “Insufficient space on the source export partition ‘/’ to accomodate all the data for upgrade data option … [Read more...]

How do I change the name of a vSwitch with vSphere 7.0 U2 and higher?

Some of you may have noticed it already, and some may not, but a lot of the configuration details that were traditionally stored in “esx.conf” have now moved elsewhere. The question is where did it go? Well it went into “configstore” and with “configstore” now also comes a … [Read more...]

Can I make a host in a cluster the vSphere HA primary / master host?

There was an interesting question on the VMware VMTN Community this week, although I wrote about this in 2016 I figured I would do a short write-up again as the procedure changed since 7.0u1. The question was if it was possible to make a particular host in a cluster the vSphere HA primary (or master as it was called … [Read more...]

HCI Mesh error: Failed to run the remote datastore mount pre-checks

I had two comments on my HCI Mesh compute only blogpost where both were reporting the same error when trying to mount a remote datastore. The error that popped up was the following: I tried to reproduce it in my lab, as both had upgraded from 7.0 to U2 I did the same, that didn’t result in the same error though. … [Read more...]

Using HCI Mesh with a stand-alone vSphere host?

Last week at the French VMUG we received a great question. The question was whether you can use HCI Mesh (datastore sharing) with a stand-alone vSphere Host. The answer is simple, no you cannot. VMware does not support enabling vSAN, and HCI Mesh, on a single stand-alone host. However, if you still want to mount a vSAN … [Read more...]

vSphere Native Key Provider backup not working

I had three people asking this question the past few weeks, they were trying to configure the vSphere Native Key Provider so that they could enable vSAN Encryption, but the backup function wasn’t working. If you have not seen the Native Key Provider in action yet, just watch the video below. As demonstrated in … [Read more...]

vSAN File Services and Stretched Clusters!

As most of you probably know, vSAN File Services is not supported on a stretched cluster with vSAN 7.0 or 7.0U1. However, starting with vSAN 7.0 U2 we now fully support the use of vSAN File Services on a stretched cluster configuration! Why is that? In 7.0 U2, you now have the ability to specify during configuration of … [Read more...]

Compute only HCI Mesh with vSAN 7.0 U2

I guess that title explains it all, starting with vSAN 7.0 U2, we now also support connecting a compute-only cluster with a vSAN cluster. Meaning that if you have a vSphere cluster that does not have vSAN enabled, you can now mount a remote vSAN Datastore to it and leverage all the capabilities it provides! I am sure … [Read more...]

How long does it take before a host is declared failed?

I had a question this week around the failure of a host. The question was how long it takes before a host is declared failed. Now let’s be clear, failed means “dead” in this case, not isolated or partitioned. It could be the power has failed, the host has gone completely unresponsive, or anything else … [Read more...]
