I put outdoor crack filler on my x90 siding to fix joints between the boards and small holes.

That was last year, this year I notice the outdoor primer and paint is already lifting and cracking on those spots.

Do I scrap it down and then reprime and paint and forget about patching the little cracks???

Crack filler is usually for masonary products. Concrete, asphalt, etc...If this is wood siding, a good latex caulk might do the trick.
Maybe you could supply more details. What was the product name of this crack filler? What are the holes in?

depending on the depth:width ratio & thickness of the applied mtl, you may have also needed to install backer rod prior to the next step.

usually selecting proper repair mtls AND method result in good performance.
