![]() In the next image, you can see that I have a 126GB, a 7TB, a 4TB, and a 9.76TB virtual hard disk present. The easiest way to do this is to open File Explorer inside the virtual machine and check each volume’s size (assuming that the virtual machine is not storing multiple volumes on a single virtual hard disk). The best way to avoid this problem is to examine each virtual hard disk to determine its maximum size. If I did that, however, I risk over-provisioning the system and having virtual hard disks run out of disk space even though Hyper-V has the illusion that there is plenty of space available. ![]() In all fairness, nothing stops me from claiming all 18.8TB of available disk space. This means that unless I specifically chose to create fixed-length virtual hard disks, the virtual hard disk files will continue to grow as data is added. The reason for this is that by default, Hyper-V creates dynamically expanding virtual hard disk files. Even though I need to add a lot of disk space to one of the virtual hard disks, I can’t claim all 18.8TB. If you look at the next image, you can see that the F: volume has 18.8TB of free disk space available. In the interest of keeping things simple, let’s assume that Mirage is the only VM that is using the F: volume. This virtual machine contains four virtual disks, all of which are stored on a physical volume named F. This is going to work a little bit different in every organization, but let me show you an example from my own environment. If you’re going to perform a virtual hard disk expansion that consumes a significant amount of the available storage space, you will need to consider how much space you actually have available to work with. Maybe you’ve got a large storage pool with a vast amount of free space available, and you only need to add a relatively small amount of space to the virtual hard disk in question. In some cases, you might not have to worry about physical disk space. Figure out how much disk space is actually available ![]() Even so, there are several things that you will need to consider before expanding a virtual hard disk. Thankfully, Microsoft’s Edit Virtual Hard Disk Wizard makes the process of expanding a virtual hard disk simple. It’s inevitable that any Hyper-V virtual machine that stores data will likely eventually need more storage space than what it was initially provisioned with.
