Good morning. I’ve been using Mailcow for 2 years now and everything works great; except, there’s a difference between the disk space I can see in the OS vs the disk space I can see in mailcow UI. I host about 10 domains. In mailcow UI / Configuration / System Information, I can see the disk usage at 96% (58GB / 64GB). Using Ubuntu (18.04) the “df” command reports 96% usage for the docker volume (matches mailcow UI). However, in mailcow UI, when I look at Configuration / Mail Setup / Domains, the “Statistics” column shows a much higher disk usage than what I can get with ncdu on the vmail folder. For example, domain 1 reports 16.0GB in mailcow UI and 12.0GB in ncdu; and domain 2 reports 7.1GB in mailcow UI and 6.2GB with ncdu; and at the other end, domain 10 reports 336MB in mailcow UI and 301MB in ncdu.
What can explain the difference?
