[SOLVED] Why is the 'data' LV much smaller that the disc?

[maeries]

I apologize if this is a noob question.
So I installed Proxmox "normally", i.e. with LVM and ext4 some time ago. Now i noticed that my SSD shows up with 223,57GiB in size under Datacenter->pve->Disks. But under Datacenter->pve->Disks->LVM-Thin the data LV is just 141,43GiB. What is the rest used for? Can I increase the LV?

The PVE installer by default splits your disk into a static LV for your host data (i.e. PVE itself) and an LVM-thin for guests. They are given about equal amounts of disk space. If you shrink your root LV correctly, you can of course extend the thin one. Make backups beforehand

Thanks. Guess I have to research the what static and thin means to fully understand your answer
