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
