Guys, I'm running ESXi 5.1 and over vSphere 5.1 I am having issues with resizing a server. I want to decrease the size of the disk space on this one server in order to make room for more servers. I've tried resizing through the Edit section of the VM both with it on and with it off. I've tried it with all of the VMs off and it still goes back to 800GB when I try to change it to something else. I cannot change this to a lower amount. Inside the VM I've checked the comp management and disk management and I have over 200GB of unallocated space. Not sure what else to do other than blow the VM away .. seems extreme for resizing space though.
