ERROR: this node should be a standby

[pizu]

Hi,

I have set 2 new servers with postgresql 12 and repmgr for the master/slave, for the primary node i manged to register with no issues, when am trying to register the standby node am having the bellow error:

INFO: connecting to local node "standbynode" (ID: 2)
ERROR: this node should be a standby (host=standbynode.domain.com user=repmgr dbname=repmgr connect_timeout=2)

I followed:
https://www.2ndquadrant.com/en/blog/how-to-automate-postgresql-12-replication-and-failover-with-repmgr-part-1/

seems i am missing something, can someone help?

Thanks.

From the provided information, it looks like the connection string for the standby (host=standbynode.domain.com user=repmgr dbname=repmgr connect_timeout=2) actually points to the primary.

You can check with this command:

psql -d 'host=standbynode.domain.com user=repmgr dbname=repmgr connect_timeout=2' -c 'SELECT pg_catalog.pg_is_in_recovery()'

If it returns f, then you probably need to ensure standbynode.domain.com connects to the correct host.
