hello team, we have large number of the ReFs volume from the nimble storage while it is using as Hyper-V CSV and have .vhdx file which are 50Tb+ CSV/ Nimbler volume. There is huge space difference, and it won't be able to reclaim the deleted space from CSV to nimble storage. while it is pretty good in VMware setup. Does anyone know best way to reclaim the space, or MS did any utility to clear the space? Creating the new CSV and format to NTFS and then migrate it hectic job as it is used and data would be putting continuous. not sure if anyone has tested this private KB - KB900645
