Reading between the lines in that post the user added a new partition on
the newly-allocated region of disk (this is fine - it's only in-use
partitions that are a problem) and then extended the VG onto the new
partition.

It's an OK workaround if you have no option but I normally prefer to
arrange some downtime and enlarge the existing partition rather than end
up with multiple PVs on the same disk (the tools work fine I just feel
it looks messy).
