please just paste the config just as Dan specified to *both* nodes. That
should work.

The idea with the DRBD configs is to tell each node about the whole
picture, and each node will pick the information it needs. That's why it
can even work when each node sees a slightly different picture.
But don't try tricking DRBD, because you will only confuse yourself.
Just install the whole, working config on each of your nodes.

HTH,
Felix
