you are not.
there is no such thing as drbd 0.8
there is only drbd 8.0.x (currently: 8.0.16)
and 8.3.y (currently 8.3.1).

and if you had used one of these mentioned "latest" releases of DRBD,
this message would have already been softened, as it apparently scared
too many people (including you).
the softened message reads
Even though it looks like this would place the new meta data into
unused space, you still need to confirm, as this is only a guess.
so you are good, your data is fine,
you may proceed.
