[ClusterLabs] Why Won't Resources Move?

I have what seems to be a healthy cluster, but I can't get resources to move.

Here's what's installed...

[root at 001db01a cluster]# yum list installed|egrep "pacem|coro"
corosync.x86_64                  2.4.3-2.el7_5.1                 @updates
corosynclib.x86_64               2.4.3-2.el7_5.1                 @updates
pacemaker.x86_64                 1.1.18-11.el7_5.3               @updates
pacemaker-cli.x86_64             1.1.18-11.el7_5.3               @updates
pacemaker-cluster-libs.x86_64    1.1.18-11.el7_5.3               @updates
pacemaker-libs.x86_64            1.1.18-11.el7_5.3               @updates

Cluster status looks good...

[root at 001db01b cluster]# pcs status

Constraints look like this...

[root at 001db01b cluster]# pcs constraint

But when I issue a move command, nothing at all happens.

I see this in the log on one node...

Aug 01 03:21:57 [16550] 001db01b        cib:     info: cib_perform_op:  ++ /cib/configuration/constraints:  <rsc_location id="cli-prefer-ms_drbd0" rsc="ms_drbd0" role="Started" node="001db01a" score="INFINITY"/>
Aug 01 03:21:57 [16550] 001db01b        cib:     info: cib_process_request:     Completed cib_modify operation for section constraints: OK (rc=0, origin=001db01a/crm_resource/4, version=0.138.0)
Aug 01 03:21:57 [16555] 001db01b       crmd:     info: abort_transition_graph:  Transition aborted by rsc_location.cli-prefer-ms_drbd0 'create': Configuration change | cib=0.138.0 source=te_update_diff:456 path=/cib/configuration/constraints complete=true

And I see this in the log on the other node...

notice: p_drbd1_monitor_60000:69196:stderr [ Error signing on to the CIB service: Transport endpoint is not connected ]

Any thoughts?
