Qubes OS release

4.1.2
4.2.0

Brief summary

Qube Manager: Disk Usage does not match df -hs /rw

Steps to reproduce

Check "Disk Usage" for a qube in Qube Manager.
Compare it to df -hs /rw in the qube.

Expected behavior

The two should match (or at least be close).

Actual behavior

The differ, often significantly (e.g. 2x).

Note: I understand this is based on private volume usage, however it doesn't give good idea of actual storage usage which is what matters to the user. In case this is assumed to work as expected, please consider this an enhancement request.

If any useful information on this issue is not already present on the other issue, please add it in a comment on the other issue. Here are some common cases of duplicate issues:
