Linux Logical Volumes

Fedora, as do other distros, freaks out when you add a physical drive to a system which had been previously part of another logical volume.  This doesn’t happen often, but if it does, the symptom is when you run system-config-lvm and it exits unexpectedly with:

'NoneType' object is not iterable

The way to resolve this is to fdisk the new disk on the system, create a partition on it, and write that partition table back to the disk.  This overwrites the previous LVM information.
