Consider a blkdev of size S1. Using LVM we increase that value under the hood to size S2, where S2 > S1. We perform an online resize from size S1 to S2. The size and alignment of any new groups added will different from the non-resize case, where mke2fs was run directly on a blkdev of size S2.
No, they won't. We simply grow the last block group in the filesystem
up to the size where we'd naturally add another block group anyway; and
then, we add another block group exactly where it would have been on a
fresh mkfs.
