Maybe it's like with the cluster: Once you have set it up correctly, it runs quite well, but the wy to get there may be painful. I quit my experiments with dual-primary DRBD in some early SLES11 (SP1), because it fenced a lot and refused to come up automatically after fencing. That may have been a configuration problem, but with the docs at hand at that time, I preferred to quit and try something else.
