LVM — Incorrect metadata area header checksum
If LVM2 shows some warnings like “Incorrect metadata area header checksum”, it’s certainly because it checks some partitions without LVM support (x8e). The filesystem works fine with this message but you can get rid of it, exclude not LVM partitions by editing /etc/lvm/lvm.conf :
filter = [ “r|/dev/cdrom|”, “r|/dev/hda1|”, “r|/dev/hda3|” ]
Use fdisk to know the partitions to exclude and run vgscan to test.
