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.

Cannot_Consolidate_Disk_Busy-01

 

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.

Cannot_Consolidate_Disk_Busy-02

 

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

Cannot_Consolidate_Disk_Busy-03

 

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

Cannot_Consolidate_Disk_Busy-04

 

Consolidate

Cannot_Consolidate_Disk_Busy-05

 

Add the Existing disk back to the VM

Cannot_Consolidate_Disk_Busy-06

Cannot_Consolidate_Disk_Busy-07

Cannot_Consolidate_Disk_Busy-08

Finally, Delete all snapshots

Cannot_Consolidate_Disk_Busy-09

 

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.
