I have a 2012 Server that Hosts HYPER V's. The host is loosing HD space rapidly. I keep the temp files clean daily. Is there a program that can monitor the server and tell me what file or folder grows the most in a given period of time?

Hi there! :)

As a start, you may try these options.

WatchDISK - Shows directory sizes over time
https://www.poweradmin.com/watchdisk/

PA Storage Monitor -  Shows directory sizes over time and more (besides tracking just directory sizes, it can tell you who the largest storage users are, where the MP3s are, etc).

Hope you find this useful :)

Open Hyper-V Manager. Are there any CheckPoints/SnapShots? Delete them. They use a differencing disk to keep things static at the point in time the CheckPoint/SnapShot was taken.

NOTE: There must be enough free space to create a new parent file when deleted!

@Philip Elder No Snapshots, but is there a way to steal back some storage space from the VM to the HOST? I know how to do the opposite, by editing the settings in Hyper V Manager, and then extending the partition in disk management of the VM, but how do I do the opposite. Was able to shrink volume in the Hyper V Manager for the Hyper V and also in it's disk management and it shows the reduction, but how to reclaim that in the HOST?

Process is pretty simple so long as there is free space in-guest.
1: Disk Manager --> Right click partition --> Shrink
2: Hyper-V Manager --> Disk --> Edit --> Shrink

That may recover some space.

Is the host storage over-committed?

@Philip Elder. Hey Phil, thanks, but isn't "Was able to shrink volume in the Hyper V Manager for the Hyper V and also in it's disk management and it shows the reduction, but how to reclaim that in the HOST?" The same thing as what you described? I see no increase volume in the host disk or option to extend drive in Disk management on the host drive. What am I missing.

Did the VHDX file that had its size reduced show that reduction in Windows/File Explorer?

A VM reboot may be required for the shrink to take.

And yes, I misread that. Sorry.

@Philip Elder. No worries I appreciate your help and thanks for responding. I did a VM reboot and also a HOST reboot and so additional storage showed for the HOST and when I went into the HOSTS  Disk Management, then option to EXPAND was not available. I am missing something. Is it is because it is not a dynamic disk? It is the OS BOOT Partition btw.

Host Disk Management would be connected to the underlying physical storage.

Expanding or shrinking a VHDX file will only reduce or free up space on the partition it is resident on.

To expand the underlying storage, thus making available space shown in the host's Disk Management, would require the addition of hard disks/SSDs to the host, a possible reconfiguration of the RAID controller, and then free space would show in the host's Disk Management.

Note that some RAID controllers do not support online expansion of RAID arrays and their logical disks.
