I didn't miss Stonith, I just didn't want it turning my server off while I work on the configuration. Surprisingly you actually managed to help me here. I had Master/Slave set for the IP address originally but that didn't work so I switched to clone. I will switch back to Master/Slave and go from there.

And you miss STONITH, a must-have for dual-primary drbd.
