Hi,

sure, drbdadm commands still work, why shouldn't they, they are lowlevel
tools.

In your case (2 nodes cluster), drbdmanage is supposed to "break" when
the second node is not there. You basically have these choices:

- 1 node (okay, a bit lame)
- 2 nodes and *both* are available. Otherwise it does not finish with
  leader election to avoid split brains.
- >2 and you have a majority
