Windows Server VM: Optimization not available

[Afox]

Hello,

I have setup a Windows Server 2019 VM and experiencing the issue that when I go to the properties of my "C"-drive and select Optimize (tools-tab) it shows me that the drive is qualified but I can´t use the optimize-button as it says "Optimization not available".

disk settings:
VirtIO SCSI
qcow2
SSD emulation on
Discard on
Cache Write back

I used the latest virtio drivers (0.1.173) for everything.

Thanks in advance for any hint.

Regards,

Afox

AFAIU disk "optimization" in Windows is basically defragmentation - which, on SSDs is not necessary. If you're physically running an HDD, disable "SSD emulation", otherwise just don't bother with letting Windows "optimize" your disks.

I believe Windows uses TRIM command when running optimization on a recognized SSD. On Windows 10 machines with the same settings the optimization button is available and working (not defragmenting, but trimming i guess).

When searching for "Windows 10 TRIM" online, none of the results mention the "optimize" window. Check here for example: https://www.windowscentral.com/how-ensure-trim-enabled-windows-10-speed-ssd-performance
