Hi Everybody,
We are running Windows 2012 R2 Hyper-V Server, and our main production server VM is running Windows 2012 R2 on a dynamic VHDX on a 700GB partition. This VM has been running successfully for about four years without much trouble.
A database application was installed last week, and since this has happened, I've seen the hard disk space being reduced day by day until now we are reaching a point where the whole partition will soon be full. Within the VM, the disk usage does not increase, but the VHDX is growing by about 8GBs per day.
What I think is happening is that there is some process that they are running at night that is copying a huge amount of information and then deleting it, which gives us a sort of white space effect. So I will have to down the server some evening to get back the white space. I'm just wondering if I should use the opportunity to change the disk to Fixed VHDX and if this would help with the problem.
Any advice appreciated.
thanks,
Jonny.
