#5526 Incorrect used disk space in dashboard

[Alexandr Shpak]

Webmin/Virtualmin dashboard says

Local disk space 88.72 GiB used / 1.02 TiB free / 1.1 TiB total

At the same time

root@host:~# du -h --max-depth=1 --total /
16K /lost+found
.....................................
32G /
32G total

32G looks much much reliable then 88

Webmin version 1.981
Ubuntu 20.4.3

Can you post the output of the command df -h on your system?

root@host:/mnt/backup# df -h

The total disk space used as shown by Webmin is the sum across all your local filesystems, and includes space that is reserved for the root user.
