Disk Consolidation FileIO Lock Error

Performing Health Checks on one of the environments when I noticed that one of the servers had a yellow icon next to it. Click on the VM and on the Summary tab it said Virtual machine disks consolidation is needed.

diskconsolidation#1

Went to the VM, right click and select edit settings > Snapshot Manager > Consolidate Disk.
The job kicked off like normal, but then the following error appeared:

diskconsolidation#2

The Solution:

vMotion’d the storage to another datastore to release the lock. Then vMotion’d back to the same datastore.

Then perform a disk consolidation and it will perform successfully.
