<div>Hi Steve,</div>
<div>i think, you have misunderstood how ip addresses are used with this setup, PGVIP should start after promotion.</div>
<div>Take a look at Takatoshi´s Wiki.</div>
<div>https://github.com/t-matsuo/resource-agents/wiki/Resource-Agent-for-PostgreSQL-9.1-streaming-replication</div>
<div> </div>
<div>The promotion sequency is very simple.</div>
<div>When no master is existing, all slaves write their current replay xlog into the node attribute PGSQL-xlog-loc during monitor call.</div>
<div>You can see all them with crm_mon -A1f.</div>
<div>Each slave gets these attributes from all node configured in parameter node_list (hopefully your node names in Pacemaker are the same as in node_list) and compares them to get the highest.</div>
<div>
<div>If the highest is this list is the own one, it sets the master-score to 1000, on other nodes to 100.</div>
<div>Pacemaker then selects the node with the highest master score and promote this.</div>
<div> </div>

<div name="quoted-content">
<div>In talking with andreask from IRC, I miss understood the need to include the op monitor. I figured it was pulled from the resource script by default.
<div> </div>
<div>I used pcs to add the new attributes and one was then promoted to master </div>
<div> </div>
<div>pcs resource add_operation PGSQL monitor interval=5s role=Master</div>
<div>pcs resource add_operation PGSQL monitor interval=7s</div>

I've built and installed the lastest resource-agents from github on Centos 6 and configured two resources
<div>
<div> </div>
<div>1 primitive PGVIP:</div>
<div>pcs resource create PGVIP ocf:heartbeat:IPaddr2 ip=10.1.22.48 cidr_netmask=25 op monitor interval=1</div>
<div> </div>
<div>Before setting up the PGSQL resource I manually configured sync/streaming replication on the three nodes with <a href="http://p1.example.com/" target="_blank">p1.example.com</a> as the master and verified that replication was working. I think removed the synchronous_standby_name from my postgresql.conf and stop all postgres services on all nodes</div>
<div> </div>
<div>1 master/slave PGSQL: -- I've the resource to use sync replication. Also I am using PGSQL 9.2.3</div>
<div> </div>
<div>pcs resource create PGSQL ocf:heartbeat:pgsql params pgctl="/usr/pgsql-9.2/bin/pg_ctl" pgdata="/var/lib/pgsql/9.2/data" config="/var/lib/pgsql/9.2/data/postgresql.conf" stop_escalate="5"<b> rep_mode="sync" </b>node_list="<a href="http://p1.example.com/" target="_blank">p1.example.com</a> p2.<a href="http://example.com/" target="_blank">example.com</a> p3.<a href="http://example.com/" target="_blank">example.com</a>" restore_command='cp /var/lib/pgsql/9.2/archive/%f "%p"' master_ip="10.1.22.48" repuser="postgres" restart_on_promote="true" tmpdir="/var/lib/pgsql/9.2/tmpdir" xlog_check_count="3" crm_attr_timeout="5" check_wal_receiver="true" --master</div>
<div> </div>
<div>I'm able to successfully get all the nodes in the cluster started and the PGVIP resource starts on the 1st node and the PGSQL:[012] resource start on each node in the cluster. The one thing I don't understand is why none of the slaves is taking over the master role.</div>
</div>
<div> </div>
<div>Also how would I go about force promoting one of the slaves into the master role via the PCS command line utility. </div>
