I am assuming this is a pretty standard thing; and nothing you need to
worry about. If you wanted to be sure, you could create a dd of the 2nd
partition, or of the first 131 MB.
Then after PV create you could do a diff on the saved data and the real
data still on disk, but I am going to assume -- as a layman -- that LVM
is not messing up the messages; it is really talking about sda5, and
there is nothing going to happen. I encounter spurious signatures all
the time, most of the time I do not even worry how it got there.
