[linux-lvm] should I be concerned that pvdisplay shows PV Size is 1024 when it's really 2047 GB?

Another oddity is if you take the PE Size and multiply it by the Total PE, then it comes out as the correct 2047 GB.  It seems like something I could safely ignore, but this is going to be a critical production server and I would like to hear from more experiences persons if I should be concerned about this:

That's a pretty old release - the current package for RHEL 5 on RHN
should be lvm2-2.02.32-4.el5. There were some display bugs fixed in
older releases, so it's worth checking with the updated package.
