Re: repmgr won't update witness after failover - Mailing list pgsql-general

hey,

I have tried to set the configuration all over again, now the status of 'repl_nodes' before the failover is:

id | type | upstream_node_id | cluster | name | conninfo | priority | active
----+---------+---------------+------------------------------------------------------------+----------+---------
1 | master |                          | cluster_name |node1| host=node1 dbname=repmgr port=5432 user=repmgr | 100 | t
2 | standby|                    1    | cluster_name |node2| host=node2 dbname=repmgr port=5432 user=repmgr | 100 | t

3 | witness|                        | cluster_name |node3| host=node3 dbname=repmgr port=5499 user=repmgr | 100 | t

repmgr is started on node2 and node3 (standby and witness) now when I kill postgresmaster process I can see in the

repmgrd log the following messages:

[WARNING] connection to master has been lost, trying to recover... 60 seconds before failover decision

[WARNING] connection to master has been lost, trying to recover... 50 seconds before failover decision

[WARNING] connection to master has been lost, trying to recover... 40 seconds before failover decision

[WARNING] connection to master has been lost, trying to recover... 30 seconds before failover decision

[WARNING] connection to master has been lost, trying to recover... 20 seconds before failover decision

[WARNING] connection to master has been lost, trying to recover... 10 seconds before failover decision

and than when it tried to elect node2 to be promoted it shows the following messages:

[DEBUG] connecting to: 'host=node2 user=repmgr dbname=repmgr fallback_application_name='repmgr''

[WARNING] unable to defermmine a valid master server; waiting 10 seconds to retry...

[ERROR] unable to determine a valid master node, terminating...

[INFO] repmgrd terminating..

what am I doing wrong?

Can you send over the output of "repmgr cluster show" before and after
the failover process?

The output of SELECT * FROM repmgr_schema.repl_nodes; after the failover
(you need to change repmgr_schema with what you have configured).

Also, which version of repmgr are you running?
