Actual PVE has only 16GB free. How can I now extend PVE + 1,8TB?

you are looking at the volume group "pve"
the thin pool is the lv pve/data
so please post the output of
Code: 
lvs

there should be a line with "data", a field "LSize" and a field "Data%"
 
Code: 
# lvs

  data pve  -wi-a-----  1.65t                                                   
  root pve  -wi-a----- 96.00g                                                   
  swap pve  -wi-a----- 62.00g
 
okay then your installation precedes 4.2, and you have a logical volume pve/data which has (nearly) the whole size of the vg.
this should be mounted under /var/lib/vz so you can use your space there
 
But a physical volume is already created?
A volume Group also:
data pve -wi-a----- 1.65t

But if I add pve, I have only 16GB
 
in this case you should not use lvm, but the local storage (the data lv should be mounted under /var/lib/vz )
 
Yes, i already read that, but I crashed the whole System in the past. Because of that I ask here for help.
What is to do now?

Thank you! :)

what do you mean by that? what do you need help with exactly?
 
I created the local storage under /var/lib/vz. Space is here 1,3TB. Is this now the space of pve data?
 
I tested it. Can still use only disc c and d.

But how to use sda and sdb? How can I mount the storage or use it from proxmox?

I created a lvm-storage in Proxmox with the group pve, but only can use 16gb of 1,8TB. How can I use the rest of /dev/pve/data?

When You create VM, chose local-lvm storage, that is pve/data LVM-Thin storage pool.

cat /etc/pve/storage.cfg
and look all storages in You pve instance.

And carefully read this link.

Maybe You need read some books...

as i said the "data" lv should already be mounted under /var/lib/vz
just use the "local" storage for your vm images/isos/templates/etc.
