So I just got a Dell T30, installed Ubuntu 16 on it. The boot drive is a 240gb SSD. I also have a 4 8TB WD Red RAID array (using RAID10).
On the dashboard of my Webmin I'm getting:
Local disk space 14.65 TB total / 13.87 TB free / 799.29 GB used
I have literally just set this up and moved only a handful of files to the raid mount. There is no way that there is 799.29 GB being used.
When I run df -h I get:
Filesystem Size Used Avail Use% Mounted on
udev 3.9G 0 3.9G 0% /dev
tmpfs 785M 27M 759M 4% /run
/dev/mapper/skillmatic--vg-root 212G 16G 186G 8% /
tmpfs 3.9G 6.6M 3.9G 1% /dev/shm
tmpfs 5.0M 4.0K 5.0M 1% /run/lock

tmpfs 785M 92K 785M 1% /run/user/1000
/dev/md0 15T 28G 14T 1% /mnt/raid
When I run du -h --max-depth=1 at / I get:
667M ./lib
28G ./mnt
4.0K ./srv
9.5G ./home
444K ./dev
17M ./etc
16M ./bin
27M ./run

18M ./sbin
12K ./media

178M ./opt
3.4M ./tmp
111M ./boot
16K ./lost+found
0 ./sys
0 ./proc
1.6G ./var
44G .
Any idea why the Webmin figure is way off?
