I am running Hyper-V Server 2012 R2 (Server Core). I have an SSD boot drive and a 10 Tb Storage Space HDD (Double Pairty - RAID6) where all VMs are stored.
I have one VM setup with an expanding VHDX file. It is setup with thin provisioning for 2 Tb and about 1.5 Tb is currently used. The VM paused due to physical disk space (SS drive) being low. I turned off this VM and tried to start a different VM that has two fixed size VHDX files (also on the SS drive). This second VM would not start either. I got the same error message, as occurred on the first VM, about the physical disk space being low. There was about 10-20 Mb of physical space left of my SS HDD when these errors occurred.
Given the first VM is setup with an expanding VHDX that makes sense to me that at some point there may not be enough physical disk space for the VM to expand and continue to run.
But given my second VM is using a fixed VHDX it doesn't make sense to me that I cannot get this VM to start. Even if the Storage Space disk were completely full I would expect this VM to be able to start?
Thanks for any assistance you can provide.
