How to regain space when switching to light client?

Hello all,
I have a Dappnode with 1tb of storage and a Geth full node running. I reached 90% of storage a few months ago and did a state purge which allowed me to gain around 20%. I reached again the 90%.
I wanted to switch to a light client to reduce the storage (but maybe misunderstood?). I did the switch and the light node is fully synchronized but it did not change anything in term of storage.

  • is there any way to reduce the size after switching to light client ?
    Many thanks in advance

Problem resolved : deleted the Geth volume from the package menu which triggered a fresh sync in light mode and it emptied the space accordingly
