Guide: Proxmox - Delete "data" thinpool and extend root partition

Have... a full root partition on proxmox?

root@kube02:~# df -h
Filesystem                            Size  Used Avail Use% Mounted on
udev                                  126G     0  126G   0% /dev
tmpfs                                  26G   21M   26G   1% /run
/dev/mapper/pve-root                   94G   94G     0 100% /

Confused because your boot disk is much larger in size?
