<div class="moz-cite-prefix">There's a lot to look at. For
starters, make sure your recovery.conf has $PGDATA/trigger as the
trigger file and not some other path. Also check the pgpool.log
to see if pgpool even tried to elect a new master.<br>
<br>
The best thing you can do after that is to su to the user pgpool
runs as on your pgpool node and run "sh -x <span
style="color:rgb(0,0,0);white-space:pre-wrap">/usr/local/etc/failover.sh
. . . " with the arguments you expect pgpool would have run and
see what it does. It could be something as simple as having to
accept an ssh host key (for which I suggest adding "-o
StrictHostKeyChecking=no" to your script's ssh command so you
don't have that problem).<br>
