You should look at the problem where cl2_lb1 is not being promoted.<br>
And I look it if you send me a ha-log and PostgreSQL's log.<br>

The following constraints means that "master-group" can not start<br>
without master of msPostgresql resource.<br>
<br>
colocation rsc_colocation-1 inf: master-group msPostgresql:Master<br>
<br>
After you power off cl1_lb1, msPostgresql on the cl2_lb1 is not promoted<br>
and master is not exist in your cluster.<br>
<br>
It means that "master-group" can not run anyware.<br>

cl2_lb1 acts as a slave? It is not a master?<br>
VIPs comes up with master msPostgresql resource.<br>

If promote action was failed in the cl2_lb1, then<br>
please send a ha-log and PostgreSQL's log.<br>

I have 2 nodes, with 2 interfaces each, ETH0 is used for an application,<br>

ETH1 is used for the Corosync configuration and VIP-REP, everything<br>
works,<br>
but if the master currently on cl1_lb1 has a catastrophic failure, like<br>
power down, the VIPs does not start on the slave, the Postgres parts<br>
works<br>
fine, cl2_lb1 takes over and acts as a slave, but the VIPs does not come<br>
up. If I test it manually, IE kill the application 3 times on the<br>
master,<br>
the switchover is smooth, same if I kill Postgres on master, but when<br>
there<br>
is a power failure on the Master, the VIPs stay down. If I then delete<br>
