[DRBD-user] 4 Node Cluster with DRBD9

[Volker Pense]

Hi,
I do have trouble with a 4-Node Cluster with RHEL7.3, Pacemaker/corosync and DRBD9. 

The Problem I have is with the configuration  of *.res:

  net {
    fencing resource-only;
   }
  handlers {
   fence-peer "/usr/lib/drbd/crm-fence-peer.9.sh";
   after-resync-target "/usr/lib/drbd/crm-unfence-peer.9.sh";
   }

This configuration only works if I put the node containing the DRBD primary in standby (pcs cluster standby <node>). It does not work on a reset of the node. 
In that case the cluster is putting all nodes on secondary and does not elect a new primary. 
The Cluster Resource is configured with the ocf:linbit:drbd resource agent. 

Any suggestions to solve that riddle?

Regards

Volker Pense
