No Volume name

I am getting warning message "Incorrect metadata area header checksum" LVM How to ask for a file on /etc/lvm/archive, I don't have any VolumeGroupName_XXXXX.vg file; seems like my system works fine, but I have the concern about this warning message. Do any of you have some idea how to fix this problem? Following are some outputs to fdisk and LVM commands
