VM disk image size bigger in Unraid GUI (Shares) v/s actual size on disk

[Zeroeth]

Hi All!

 

I have this strange issue where the VM disk image size is bigger in the Unraid GUI (when we see the folder within the Shares) compared to when seen on disk (either with MC or Krusader). The VM is on my SSD drive.

 

Example, as posted below, is of a Windows 10 VM with a disk image size of 60G but its showing as 64.4G on the Unraid GUI (Shares).

 

>> in Unraid GUI (Shares)

 

>> in MC

 

I have multiple VMs running with bigger disk image sizes resulting in Critical Disk Utilization notifications because of this.

 

Anyone else facing such an issue? and is there a way to resolve this so that the image size does not exceed the defined 60G?

Most of the GUI uses SI units, but the VMs are created with binary units, if you want the vdisk to have 60GB create one with 55.88GiB.

Thankyou for the clarification. Makes sense now as all my VM disks are reflecting in the same way on the GUI.

 

These are the various disk sizes that I have and all reflect a bigger size in the GUI.

 

61,440 MB on disk (60GB) > 64.4 GB in GUI (Shares)

81,920 MB on disk (80GB) > 85.9 GB in GUI (Shares)

256,000 MB on disk (250GB) > 268 GB in GUI (Shares)

512,000 MB on disk (500GB) > 537 GB in GUI (Shares)
