Description

creating a rbd image with size 0 is allowed in bobtail but not on argonaut.

on a mixed cluster running argonaut[burnupi07] and bobtail[burnupi06], creating a rbd image of size 0 on bobtail node and trying to use the rbd image on a argonaut node crashes rbd.

on burnupi06 : rbd create img_0 --size 0
on burnupi07: rbd cp img_0 img_new - hung and crashed rbd.
