VMware vSphere – Troubleshoot consolidating disks error

Release date: March 13th 2020

Welcome to my VMware vSphere series. As many of my visitors gather, I work mainly with Digital Workspace tasks. But recently, as I was in a process of exporting a vm to an OVF Template, I remembered that I had forgotten to delete my snapshot. I therefore canceled this operation, and immediately got the message below that consolidation was needed.



When I tried to consolidate the disk on this VM, I got the error below. I next tried creating a new snapshot and delete all snapshots, this did not resolve the error. A reboot of my ESXI-servers was also tried, without the desired outcome.



When I investigate on the storage, I can see that I have one snapshot still present



After spending some time on Google, I came across Erik Zandboer’s solution to this here: Snapshot Consolidation needed – Which with my luck… fails

His solution, which fixed my problem is, in short, this:

Shut down the VM and remove the disk that is creating this error from the VM, without deleting it from the datastore






Add the Existing disk back to the VM




Finally, Delete all snapshots



With that, the problem was fixed. A BIG thanks goes out to Erik Zandboer for this solution, saved me a lot of time and my Horizon desktop is now working excellently again.
