OK, I removed that :)

If I am not mistaken, adding

    	printf("%ju\n", rel);

at the begining of the function str2bytes should be enough, well I am
sorry to say that it prints: 3492003971072, about 3 TB, which is
compatible with the proposed 1665117 MB for the file size.

So I went back one step further and looked at smf_fsspace; the values
in fsst.f_bsize and fsst.f_bavail are consistent with the value of
rel, but are not corresponding to the size available in the file

I will dig a bit further and keep you posted.

Best regads,
