Hi All,

We have one master and one replica(15.6) postgres in primary datacenter on platform openshift version 4.14.

We are looking for DR set up , for postgres in another datacenter in RHOS running on Hyper converged infrastructure fusion.

Kindly help me with som points

We are already using patroni.  With the postgres operator, we have pgbouncer, pgbackrest and 2 nodes for postgres.

If we want to perform the same as DR setup , how do I replicate pgbouncer, pgbackrest and  postgres ?

What configuration changes I have to make in pgbouncer, pgbackrest, patroni and postgres? Some hint or idea on this if not in detail?

This is likely too complex an ask for a mailing list. My recommendation 
is that you get help from a company that knows well how to run 
PostgreSQL on Openshift. For example:

https://www.crunchydata.com/products/crunchy-postgresql-for-kubernetes

Hello,

What's the real issue? On this page, I don't see anything to block your DR system. You can make it with Patroni again when you create the PostgreSQL just up your cluster with Patroni. There is no block, you should revise your configs for the third node. 

My advice is to test environment on your local and try. It's the best way to see what you need to do.

Hi Rajesh

Question: Do you need streaming replication to this new DR primary Node from the previous DR Cluster?
 
Take a base backup from your existing primary DR PG instance using pg_basebackup or pgBackRest.  

Transfer this backup to your new DR site.  

Restore the backup to your new DR PostgreSQL instance. Ensure that the recovery settings (like restore_command) are properly configured to fetch WAL files.  

Configure your primary PostgreSQL instance to archive WAL files.  

Enable streaming replication for the standby node as you have made changes in conf in previous DR.

Then 

You have to do it manually by installing PGbouncer and Patroni.

You can use the `patroni.yaml` file from the previous DR setup, adjust it for the new DR environment with the Postgres cluster, and do the same for the PGbouncer configurations.

But all of this needs to be done on a local machine first.

So we should have two pgbouncer, two pgbackrest ?

Yes for each node to function separately, you have to setup both on them.
