I cleated the CIB and re-created most of it with your suggested parameters. It now looks like: node $id="739377522" ct1 node $id="739377523" ct2 node $id="739377524" ct3 \ attributes standby="on" primitive drbd_disc0 ocf:linbit:drbd \ params drbd_resource="disc0" \ meta target-role="Started" \ op monitor interval="19s" on-fail="restart" role="Master" start-delay="10s" timeout="20s" \ op monitor interval="20s" on-fail="restart" role="Slave" start-delay="10s" timeout="20s" ms ms_drbd0 drbd_disc0 \ meta master-max="1" master-node-max="1" clone-max="2" clone-node-max="1" notify="true" target-role="Started" location cli-prefer-drbd_disc0 ms_drbd0 inf: ct2 location cli-prefer-ms_drbd0 ms_drbd0 inf: ct2 property $id="cib-bootstrap-options" \ dc-version="1.1.10-42f2063" \ cluster-infrastructure="corosync" \ stonith-enabled="false" \ no-quorum-policy="stop" \ symmetric-cluster="false" I think I’m missing something basic between the DRBD/Pacemaker hook-up. As soon as Pacemaker/Corosync start, DRBD on both nodes stop. a “cat /proc/drbd” then just returns: version: 8.4.3 (api:1/proto:86-101) srcversion: 6551AD2C98F533733BE558C and no details on the replicated disc and the drbd block device disappears.
