[root@virt-125 ~]# pcs resource create dummy1 ocf:heartbeat:Dummy
[root@virt-125 ~]# pcs resource create dummy2 ocf:heartbeat:Dummy

[root@virt-125 ~]# pcs constraint order start dummy1 then dummy2
Adding dummy1 dummy2 (kind: Mandatory) (Options: first-action=start then-action=start)

	> OK: A detailed resource status is present

# Creating clone
[root@virt-125 ~]# pcs resource clone dummy1
> OK, 'Resource status on nodes' shows status on both nodes, on which the resource is running, automatically created a 'dummy1-clone' resource, above 'dummy1' in resource display

# Click on 'Attributes' within dummy1

	> OK: Both nodes are in the list and have 'Status' and 'Quorum' state
# Click on one of the nodes (virt-125 in this case) 
	> OK: In the detail, there is information about Resources on node, Node Daemnos (corosync, pacemaker, pcsd, sbd) and Pacemaker

# Click on 'Fence Devices'
	> OK: The fence devices are present in the list, so far without any details

# Click on 'Clusters' to get dashboard
	> OK: The cluster is present in list, with zero Issues, 2 Nodes, 2 Resources and 2 Fence devices

# Removing resources and fence devices
