Not using whole partition? Not enough storage displayed

Nextcloud version: 19.0.1
Operating system and version: Ubuntu 18.04.4 LTS (GNU/Linux 4.15.0-112-generic x86_64)
Apache or nginx version: nginx/1.14.0
PHP version: PHP 7.2.24

I’ve added NextCloud as a Network Drive on Windows 10 (using WebDav), but when I right click the drive and click properties, there is apparently 134GB of used space and a total capacity of 930GB. First, the used space seems absolutely way too high, this is a fresh install of Ubuntu 18.04 and there are no files in NextCloud, so I’m not sure where that’s coming from, if anyone has any ideas… But the real reason I’m posting here is because of the 930 GB thing, that seems wrong. The server has 2TB of storage, and doing df -h confirms this, as this is the output:

Filesystem      Size  Used Avail Use% Mounted on
udev            3.9G     0  3.9G   0% /dev
tmpfs           788M  704K  787M   1% /run
/dev/sda2       1.8T  3.3G  1.7T   1% /
tmpfs           3.9G     0  3.9G   0% /dev/shm
tmpfs           5.0M     0  5.0M   0% /run/lock
tmpfs           3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/sda1       487M   79M  379M  18% /boot
tmpfs           788M     0  788M   0% /run/user/0

As you can see, the drive has 1.7TB of storage available, which doesn’t show up (it also doesnt have remotely close to 134GB of space used, weird…)

lsblk gives this:

NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0  1.8T  0 disk 
├─sda1   8:1    0  511M  0 part /boot
├─sda2   8:2    0  1.8T  0 part /
└─sda3   8:3    0  511M  0 part [SWAP]

I just am a bit confused by why it’s not reporting the correct usage or available storage. I thought maybe it could be because there were 2 users with Unlimited storage and it was splitting it across, but I changed one of them to 1GB, and it still only shows 930GB.

I’d be very appreciative to any ideas you guys have as to what could be causing this & what could be the solution… Thanks!

…I am actually braindead, now that I am looking at it compared to my C: drive on Windows… I’m noticing a bit of a similarity… yeah, they’re the same :man_facepalming:
