It is a partial revert of commit 758b327cf5a7 ("Grow: Remove unnecessary optimization"). For native metadata component size is set in kernel for entire disk space. As external metadata supports multiple arrays within one disk, the component size is set to array size. If component size is not updated prior to array size update, the grow operation fails.
