We use properties of small resolutions of the ordinary double point in dimension three to construct smooth non-liftable Calabi-Yau threefolds. In particular, we construct a smooth projective Calabi-Yau threefold over F3 that does not lift to characteristic zero and smooth projective Calabi-Yau threefold over F5 having an obstructed deformation. We also construct many examples of smooth Calabi-Yau algebraic spaces over Fp that do not lift to algebraic spaces in characteristic zero.
