We created a new virtual machine in VMware that is using a Datastore of 2.7 tereabytes. It is the only virtual machine on that datastore. The virtual machine was created with it's original virtual drive space of 100GB. That would theoretically leave 2.6 TB of remaining space to create additional virtual drives that the operating system (Windows Server 2008 R2) could recognize. When we try to create an additional virtual hard drive of 1TB it says that there is not enough space available to do that. We also tried to expand the existing virtual hard drive to greater than 1TB , but the maximum it will allow us is 768GB. What are we doing wrong. We and to create two additional virtual hard drives that the OS will recognize, each of 1TB in size.
