Scott, saving your /etc/lvmtab* you can reactivate your VG in case something else might go wrong by restoring it and "vgchange -ay". Writing a partition table to /dev/sdb overwrote the PV part of LVMs metadata on that disk. Give vgcfgrestore a try on /dev/sdb. Please don't forget to bakup /etc/lvmconf/ regularly.
