manage storage lvm-thin: % used

[elettrodata4]

Good morning,
we are carrying out tests.
We created lvm-thin storage.
On this storage we have installed a 15 Giga VM.
we have filled this VM 95% and consequently the space occupied inside the LVM-thin storage has increased.
We then eliminated 6 GB from the VM, but for the LVM-thin storage the percentage of use remained unchanged.
How can we update this value to reflect the current value of the data contained in the VM?
Thank you

"trim" is your friend this way. Perhaps better read a little bit more about LVM-thin first to understand what happened under the hood before testing
