Possible ambiguity when combining partition table signature and LVM PV signature

Issue

When a device already contains a PV (PhysicalVolume) signature, it is still possible to create a partition table on such a device - partitioning tools (like fdisk) do not check if there are any existing signatures when creating the partition table signature. The partition table signature can coexist with the PV signature because each one has different offset within the device and the signatures do not interleave.

Example issue caused by this can be seen in Pre-existing LV's created on a RHEL 6 system are not activated on boot on RHEL 7
