A significant amount of time ago, there was an off-by-one error in a size
calculation used by softraid(4) (I'd have to go dumpster diving to find the
exact commit that fixed it) - I suspect you've got an old softraid volume
that was disklabelled with the incorrectly reported size. It is likely
harmless and has probably been that way since it was created, however if you
want to fix it you could follow Otto's instructions.
