Your workflow is strange. What are you trying to accomplish here?

Your steps in 5 should be:

vgreduce vg01 /dev/vdc /dev/vdc
pvremove /dev/vdc /dev/vdd

That way you ensure there's no leftover metadata in the PVs (specially
if you need to attach those disks to a different system)

Again a usecase to understand your workflow would be beneficial...

Cheers
