The upstream Redhat bug is closed as NOTABUG, but the situation was not discussed there properly. There was an assumption made that the partition was part of a software raid array at some point. This was not the case for me (brand new disk when installed, only ever in one layout), however it was an LVM partition, so resizing it slightly fixed the problem.
