            <div>But only on one S2 works fine, on the others stops with
              only "Overview building failed".</div>
            <div>My command is simply "gdaladdo -r nearest path".</div>
            <div>I noticed that it will work if I specify to just up to
              16 the OVR levels, but as soon as I put 32 it fails. (as
              said on one S2 works fine)</div>
