The stripe-size is the most efficient size to write to RBD images. However, not all images are a multiple of stripe-size large. That means thick-provisioning would not allocate the full image, and the process might even fail. This adds a 50 MB PVC to test the process, 100 MB is coincidentally a multiple of the (default 4 MB) stripe-size, 50 MB is not. Signed-off-by: Niels de Vos <ndevos@redhat.com>
