If the top image to commit is the active layer, and also larger than the base image, then an I/O error will likely be returned during block-commit. For instance, if we have a base image with a virtual size 10G, and a active layer image of size 20G, then committing the snapshot via 'block-commit' will likely fail. This will automatically attempt to resize the base image, if the active layer image to be committed is larger.
