pvremove is the opposite of pvcreate - it removes the LVM label from the
device that you want to remove from the LVM system and use for something

It is *not* a replacement for vgreduce.

Obviously the warning needs to be made clearer - you need to think
carefully about what you're doing before using -ff.
