Mario, Thank you for the review.
Yes, there is free space in the LVM. I have gone through the manual many times (today and the last several months) and don't see a method to add a pv or vg. It seems to add a pv, it needs a device. And to add a vg, it needs a pv. How can I add either? Displaying the resize pv: # pvdisplay -v -m DEGRADED MODE. Incomplete RAID LVs will be processed.
