In your case you could ssh to your permanent slave (which is not known to pgpool) and execute the postgres command to follow the new master.</div><div><br></div><div>Lazara,</div><div><br></div><div>Is it possible to use pgpool for load balancing and repmgrd for automatic failover ? I could not understand how to make this work. Is it enough to leave the pgpool configurations for failover script and follow_master script empty ? Is pgpool going to automatically detect that there is a new master and restart the child processes ?</div><div><br></div><div><br></div><div>Pierre</div><div><br></div></div><div><br></div><div><br></div><div id="ydp185476a9yahoo_quoted_6688933274" class="ydp185476a9yahoo_quoted"><div style="font-family:'Helvetica Neue', Helvetica, Arial, sans-serif;font-size:13px;color:#26282a;"><div>On Thursday, June 1, 2017, 3:29:50 PM GMT+2, Lazaro Garcia <lazaro3487@gmail.com> wrote:</div><div><br></div><div><br></div><div><div id="ydp185476a9yiv0998764849"><div><div class="ydp185476a9yiv0998764849WordSection1"><p class="ydp185476a9yiv0998764849MsoNormal"><span lang="EN-US" style="font-size:11.0pt;">For that you can use repmgr for controlling the replica, promoting new master, and follow the slaves to new master and pgpool for load balancing, and HA of the cluster.</span></p><p class="ydp185476a9yiv0998764849MsoNormal"><span lang="EN-US" style="font-size:11.0pt;"> </span></p><p class="ydp185476a9yiv0998764849MsoNormal"><span lang="EN-US" style="font-size:11.0pt;">Regards.</span></p><p class="ydp185476a9yiv0998764849MsoNormal"><span lang="EN-US" style="font-size:11.0pt;"> </span></p><div class="ydp185476a9yiv0998764849yqt5192638334" id="ydp185476a9yiv0998764849yqt29025"><div><div style="border-style: solid none none; border-top-width: 1pt; border-top-color: rgb(225, 225, 225); padding: 3pt 0cm 0cm;"><p class="ydp185476a9yiv0998764849MsoNormal"><b><span style="font-size:11.0pt;">De:</span></b><span style="font-size:11.0pt;"> pgpool-general-bounces@pgpool.net [mailto:pgpool-general-bounces@pgpool.net] <b>En nombre de </b>Avi Weinberg<br clear="none"><b>Enviado el:</b> jueves, 1 de junio de 2017 09:09 a. m.<br clear="none"><b>Para:</b> pgpool-general@pgpool.net<br clear="none"><b>Asunto:</b> [pgpool-general: 5548] Re: Server to never assume the role of master</span></p></div></div><p class="ydp185476a9yiv0998764849MsoNormal"> </p><p class="ydp185476a9yiv0998764849MsoNormal"><span lang="EN-US" style="font-size:11.0pt;">Hi,</span></p><p class="ydp185476a9yiv0998764849MsoNormal"><span lang="EN-US" style="font-size:11.0pt;"> </span></p><p class="ydp185476a9yiv0998764849MsoNormal"><span lang="EN-US" style="font-size:11.0pt;">Thanks for the quick reply! </span></p><p class="ydp185476a9yiv0998764849MsoNormal"><span lang="EN-US" style="font-size:11.0pt;"> </span></p><p class="ydp185476a9yiv0998764849MsoNormal"><span lang="EN-US" style="font-size:11.0pt;">I think it will not be that simple in my case since I want the "permanent slave" server to point to the new master when there is a failover.
