6.2.2. Asymmetrical "Opt-In" Clusters
To create an opt-in cluster, start by preventing resources from
running anywhere by default
crm_attribute --attr-name symmetric-cluster --attr-value false
Then start enabling nodes. The following fragment says that the web
server prefers sles-1, the database prefers sles-2 and both can
failover to sles-3 if their most preferred node fails.

  &lt;constraints&gt;
    &lt;rsc_location id="loc-1" rsc="Webserver" node="sles-1" score="200"/&gt;
    &lt;rsc_location id="loc-2" rsc="Webserver" node="sles-3" score="0"/&gt;
    &lt;rsc_location id="loc-3" rsc="Database" node="sles-2" score="200"/&gt;
    &lt;rsc_location id="loc-4" rsc="Database" node="sles-3" score="0"/&gt;
  &lt;/constraints&gt;
Example 6.1. Example set of opt-in location constraints

At the moment you have symmetric-cluster=false, you need to add
location constraints in order to get your resources running.
Below is my conf and it works as expected, pbx_service_01 starts on
node-01 and never fails back, in case failed over to node-03 and
node-01 is back on line, due to resource-stickiness="1000", but take a
look at the score in location constraint, very low scores compared to
1000 - I could have also set it to inf

Yes but you don't have groups defined in your setup, having groups
means the score of each active resource is added.
