A general question: I have a Corosync+Pacemaker with DRBD setup on Linux; I'll
give the details if it's relevant. Corosync+Pacemaker controls DRBD start, stop,
and promotion. I've implemented fencing via STONITH as Corosync resources.

I have not put fencing in the drbd.conf file; I was under the impression that
Corosync+Pacemaker would take of STONITHing a node if there's a DRBD problem. Is
this correct? Or should I have fencing/STONITH configured in both Corosync and

Does the answer change between a primary/secondary versus dual-primary setup?
