    Thinning vs shrinking

    BobSimon Novice

      VMware ESXi, 6.5.0, 8294253

      I want to reclaim unused space from a VM back to the datastore.  I used vSphere Web Client to clone the VM to thin then used Computer Management/Disk Management to shrink the volume with 30GB now unallocated.


      The following article on thinning and shrinking left me wondering about differences between these two activities.

      Growing, thinning, and shrinking virtual disks for VMware ESX and ESXi (1002019)

      1. Can someone explain this?


      2. Will vmkfstools -K reduce the size of the .vmdk by 30GB?  If so, will the datastore show up with 30GB more free space in vSphere Client?
