I have a linux vm with 40GB Thick provision Eager Zeroed. when I login to my ESXI Server I can see that the folder of the VM is about 40GB. I've created a 10GB file on the linux VM machine. I see that the VM folder on the ESXi grew in 10 GB. I decided to delete the file on the Linux machine and thought the VM folder on the ESXI will shrink as well but it stayed the same as it was after I added the 10GB file.
is it because I'm using Thick provisioning or this is the way VMware VM works? why didn't the VM folder on the ESXi shrink back to the default size once I deleted the 10GB file?
