...what is it connected to? I wonder.

Getting both your local nodes in Secondary/Secondary is fine. The you
must make one Primary and bring up the stacked resources.

If you do get split brain between your local stacked resources and the
remote resources, you do have to resolve it as hinted by Andreas.

Bear in mind that your victim has stacked resources, you will have to
discard its data using drbdadm --stacked.

HTH,
Felix
