<p class="MsoNormal">I have a 3 nodes setup for pgpool/postgresql using watchdog, When testing the failover of pgpool, I turn off pgpool on node 1 which fails over watchdog to node 2. Then I turn on pgpool on node 1 that set node 1 as a standby node. The next
step I turn off pgpool on node 2 which watchdog try’s to fail over to node 3 but watchdog IP never comes up on node 3 or any of the nodes. So I turn off pgpool on node 3 and watchdog fails over to node 1.
<o:p></o:p></p>
<p class="MsoNormal">My question is why watchdog doesn’t come up on node 3. Pgpool.conf is set the same on all 3 nodes.<o:p></o:p></p>
