How did you upgrade? Anaconda, or up2date, yum or something else that couldn't possibly have fixed things up?
I don't know whether Anaconda does anything to fix LVM upgrades, but I vaguely remember some note about this not working in FC2 test releases Release Notes, and I can't find it in the FC2 final release notes, so I assume it should work.
Anyhow, if it doesn't, or if you chose one of the other upgrade paths, the way to fix it is to remove the LVM1 device nodes from the VG directories. After that, a reboot should fix things up. If it doesn't, run as root, after entering the password when the system fails to boot up:
mount -o remount,rw / echo mkdmnod | nash vgscan vgchange -ay vgmknodes
this was required in early FC2 test releases, when initrd attempted to use device nodes from the root filesystem, instead of from initrd. I don't think this should still be necessary, but if everything else fails, it's worth a shot.
After setting things up, you may want to re-create initrd, just in case.
