^^^ this. I run too close to our used limit thresholds to wait weeks/months for the free to be returned. For VMware, it is easier for us to just migrate the VMs to a new DS and remove the old.
I run a custom script each weekend that compacts each CPG one at a time (on each frame) because again I can have instances where I will have 1TB or more sitting free in a CPG and AO doesn't trigger a compact CPG.
