Don't use the whole free space when resizing  partition to a larger size on a disk with non zero stripesize (e.g. disks with 4k sector size)[1]. Also do not use automatic alignment when size is exactly specified, but an alignment is not. Use automatic alignment only for case when user omits both "-s" and "-a" options.
