First, thanks for this project!
I'm try your cms in virtual machine (Vmware Workstation 12)
I have installed Ubuntu Server 16.04 x64 with 2GB RAM, 1 cpu with 2 core and 100GB vmdk

I have used setdisk for my user (20GB)
Quota mount on "/"
For the test, I transferred a 200MB file with WinSCP in /home/username/torrent
I tried "fix-disk_widget_root" and reboot virtual machine but it's same issue
With showspace, the used space it is good
The Used space in dashboard dont update
