Hello, first of all, always very thankful for a great application, I have always been a big webmin fan and user.
Last night I just installed a small little virtual server for some home testing, I decided to use the ubuntu server for simplicity's sake, I gave the virtual disk image a size of 2TB (Dynamic), and when I logged in to webmin I noticed an exagerated disk size in use, which for a basic debian-like server with no GUI and fresh install was just a bit too much.
I am running the virtual server in VirtualBox 4.2.16 and the server is ubuntu 12.04.2 (32bit), the virtual drive was created with ext4 no LVM, so I just thought maybe I should report this to you, I'm not sure if this is happening because of the virtualization.
I'm attaching a screenie of my webmin highlighting the disk usage.
Thank you very much.
