Finding differences between used space in a VM and VHD size This topic contains 2 replies, has 2 voices, and was last updated by Bruce 4 months, 4 weeks ago.

It would be good to run a script to determine the amount of white space, so that we can (provided the VHDX is dynamic) migrate the VHDX to another volume to release the white space. I script that checks the VM used space, then the VHDX size to flag up white space.... Any help appreciated!

The problem and fix I have is on this site: How To Reclaim Unused Space In Dynamic VHDX In Windows Server 2012 R2 & Hyper-V? #HyperV #WS2012R2 #WS2012 I need help putting together a script that can show me all VMs with claimed whitespace.
