Our file server is Windows 2008 R2 virtual server running on VMware ESXi 5.1. The file server has four virtual disks located on different datastores. One of the virtual disks is 1.8TB, in windows it has 500GB of unallocated space. I want to remove the unallocated space and shrink the virtual disk. I cannot use VMWare Tools because the virtual disk is thick-provisioned.
What is the best way to shrink the virtual disk and reclaim the unallocated space in VMWare vCenter?
