How can I shrink "local" and increase the size of "local-lvm"?

[maeries]

My server runs on a 240GB SSD. The local-lvm is nearly full (~90%) while "local" is nearly empty. Is it possible to shrink the local storage and then expand local-lvm?

The "local" is a directory and the ''local-lvm' is a lvm-thin pool by default. The path of the "local" is actually on a lvm volume called pve-root，while the "local-lvm" is on another lvm volume called pve-data. Pve-root and pve-data are on the same volume group called pve. So you have to reduce pve-root first in order to increase pve-data if there's no extra spaces on lvm group pve and SSD. But I don't think it's a good idea because shrinking lvm volume could cause data loss. But if there's extra space left on SSD, you can increase vg pve first, then you can increase lv pve-data. I'm just a user , not a professional.

and can only be done in offline mode, so you need to boot a live linux and change it from there.
