Okay, so now you've got (42766318+694273)*3KB=124GB of data, and 223GB
used. I guess your OSD journals are 512MB each, so that's another
16GB, which still leaves more unexplained space usage than I would
expect.
But it's probably just some peculiarity of how your system is set up;
you could check and see how the numbers change when you add new
objects to the system to make sure it's just a base case rather than
something to worry about. :)
