Question about pacemaker + heartbeat + postgres in active/passive configuration

Hello everyone,

Apologies if this is not the correct group for this question, but I am seeking information on how to set up pacemaker with heartbeat and postgres in an active/passive streaming (pg 9.1) configuration. I would prefer to use heartbeat and not corosync, although most of the good tutorials like the Cluster_from_scratch document use corosync with pacemaker, but I don't have any shared storage to use it with on my machines.

The presentation by Keisuke Mori of Linux-HA Japan is beautiful and exactly what I really want to do, but I need more information on how to use pacemaker with heartbeat instead of corosync. Does anyone know of a recipe or tutorial that goes through what his presentation shows?

Kind regards,
-Renee

Assuming pacemaker was built with heartbeat support, simply install
heartbeat and add:

crm respawn

to ha.cf

Start heartbeat, job done.
Resource configuration is unchanged from what you see in Clusters from Scratch

Re: Question about pacemaker + heartbeat + postgres in active/passive configuration [In reply to]

Hi, Andrew. Where can I find the presentation by Keisuke? Btw, I use heartbeat in combo with pacemaker also...but with MySQL...was just a decision based on an impression at the time that most of the documentation content was about heartbeat...and that heartbeat had a more stability. And it seemed that there was nothing negative being posted that would deter me about the choice. After being on this distribution list for a while, I now think it's time for me to move to Corosync.

No idea sorry. Renee seems to know though, maybe he can help.

Hi,

Yes, that is it. Thank you for finding and sharing it :).

The developer's wiki page provides more up-to-date information for
pgsql RA after it has included to the upstream:
https://github.com/t-matsuo/resource-agents/wiki/Resource-Agent-for-PostgreSQL-9.1-streaming-replication

As for the configuration for heartbeat, documents from linux-ha.org might help:
http://www.linux-ha.org/doc/users-guide/_creating_an_initial_heartbeat_configuration.html

Regards,
Keisuke MORI
