Sorry to be dense, but I don't feel confident about proceeding before I know what the next step should be. I am pretty sure that I can remove the "lost" PV, using the instructions that I have found in multiple places, including the referenced slide deck, but I have not been able to find anything about recovering the LV that spans from the existing PV into the lost one. Since most, if not all of the existing data from that LV is on the "good" PV, I would hope that I can recover that filesystem.

The second entry shows "unknown device(0)".
