- when we open an image, open the parent image too. - make reads fall through to parent - guard writes beyond parent size with object existence check - on failure, attempt copyup and retry test plan: - create child, read child, compare to parent - create child, modify child, compare to parent - resize child (up, down, both), verify we get the correct fall-thru behavior - modify librbd_fsx to periodically create a child and shift new work to it
