I've configured a two-node DRBD cluster with a handful of resources/volumes. Each of the volumes is exported/shared from the DRBD primary node using iscsitarget (iSCSI Enterprise Target - IET). The secondary node is not exported/shared using iSCSI - It's only a duplicate of the primary node.

How can I use Corosync+Pacemaker to make the iSCSI service highly available using the DRBD secondary node?
