When you bring up system-config-lvm, /dev/sdb2 should show up in the "Uninitialized Entities". Click on "Initialize". After that is done /dev/sdb2 should move to "Unallocated Entities". Then you'll see a choice to "Add to existing Volume Group". -- People will accept your ideas much more readily if you tell them that Benjamin Franklin said it first.
