high disk space consumption

Hi heroes,
I'm currently running pve 7.3.3, from web control panel i can see the current disk space usage is 66% as below:


I have 2 disks mounted, 2TB SSD (pve installed on SSD) + 1TB HDD
but df -hT and lsblk show something like below:


I was also trying to find biggest folders by using something like "du -ah / --max-depth=1", but the output also confused me, may be a basic linux disk storage question (maybe LVM mechanism?), but can someone give some suggestions on why my disk usage is 66%(1.76TB/2.66TB)? pretty sure my disk usage should not be this big... thanks in advance!

as you are using an LVM-thin pool - have a look at that, either in the web-interface (probably named local-lvm). That's where (some, at least, according to the first screenshot) VM disks/snapshots are stored that are probably taking up the space.

You can also run lvs -a, which will list all volumes in the LVM-thin pool, their size and their currently used percentage of the allocated space.

Hope this helps!
