[pgpool-general: 7675] Failover question

[Wolf Schwurack]

I have a 3 nodes setup for pgpool/postgresql using watchdog, When testing the failover of pgpool, I turn off pgpool on node 1 which fails over watchdog to node 2. Then I turn on pgpool on node 1 that set node 1 as a standby node. The next step I turn off pgpool on node 2 which watchdog try’s to fail over to node 3 but watchdog IP never comes up on node 3 or any of the nodes. So I turn off pgpool on node 3 and watchdog fails over to node 1.
My question is why watchdog doesn’t come up on node 3. Pgpool.conf is set the same on all 3 nodes.

Here’s my output of show pool_nodes

 node_id | hostname  | port | status | lb_weight |  role   | select_cnt | load_balance_node | replication_delay | replication_state | replication_sync_state | last_status_change

---------+-----------+------+--------+-----------+---------+------------+-------------------+-------------------+-------------------+------------------------+---------------------

 0       | pgtest-01 | 5432 | up     | 0.500000  | primary | 2003       | true              | 0                 |                   |                        | 2021-08-24 14:06:20

 1       | pgtest-02 | 5432 | up     | 0.500000  | standby | 667        | false             | 0                 | streaming         | async                  | 2021-08-24 14:06:20

 2       | pgtest-03 | 5432 | up     | 0.000000  | standby | 0          | false             | 0                 | streaming         | async                  | 2021-08-24 14:06:20

Not sure if this is an issue but the lb_weight show node 1(pgtest-01) and node 2(pgtest-02) as 0.5000 and node 3(pgtest-03) as 0.0000

In pgpool.conf I have backend_weight for each node set to 0.3

Hosts = Ubuntu 20.4
Pgpool = 4.2.4
PostgreSQL = 12.8
