DRBD what is the meaning of warning "nothing to do in stacked mode"

Question

We just installed DRBD on one node (the second one is not installed).

After doing

drbdadm primary theres
service drbd start

everything is ok (resource available) but the following warning message appears

WARN: nothing stacked for this host (node01.com), nothing to do in stacked mode!

Using drbd 8.4.6, config:

global {
        minor-count 1;
        usage-count no;
}

resource theres {
        protocol C;

        on node01.com {
                device /dev/drbd0;
                disk /dev/dxcd0e;
                address 10.10.10.1:7788;
                meta-disk internal;
        }

        on node02.com {
                device /dev/drbd0;      
                disk /dev/dxcd0e;           
                address 10.10.10.2:7788;  
                meta-disk internal;     
        }

        disk {
                on-io-error detach;     
        }

        net {
        }

        syncer {
                rate 80M;               
        }
}

This didn't appear before upgrading to that version.

When you have an three-node setup, the 3rd is called "device stacked". You can see — Jose Raul Barreras, May 23 '15 at 21:05
With the data provided in your config, we have a two-node configuration. — Jose Raul Barreras, May 26 '15 at 04:06
So the meaning is that since there is only two hosts, drbd does not have to process a stacked device - why the need of a warning in this case? In earlier versions that warning did not appear. — Déjà vu, May 26 '15 at 15:01
