Too high disk storage usage question

[shimmy_jimmy]

Hi,
I usually take care about storage usage on my PC and app about total disk usage on system tray shows that I currently use 110 GiB, but when I sum up total disk usage from Qube Manager it’s around 77 GiB. varlibqubes shows 39% of data that is assigned to 19.5 GiB. vm-pool shows 57.7% for data and 40.1% for metadata that is assigned to the rest.
Can someone tell me where is my 33 GiB? Dom0 that doesn’t show it’s storage in qubes manager isn’t that big, I checked 10 biggest folders, it’s not higher than 50 MiB.

Lv of a qube takes more space than filesystem on it

The Qubes OS is storing 1 old revision of the all volumes, so when you’ve restarted vault qube a few times the old revision which still had the raw image was removed and replaced with the one where you’ve removed the raw image. Not sure how LVM works, but I guess it’s not the real space that vault volume consumes but just the maximum to which it was expanded.
