Ouch, I hadn't realized that part of the user's guide was so easily 

resource r0 {
  on alice {
    device /dev/drbd0;
    disk   /dev/drbd/r0;
  on bob {
    device /dev/drbd0;
    disk   /dev/drbd/r0;

This means the backing devices are LVM logical volumes named "r0" in a Volume 
Group named "drbd". It says so in the text above the config snippet, but 
apparently that is easily overlooked.

I will change this to a generic foo/bar "naming convention" to avoid 

Thanks for pointing this out.
