[pgpool-general: 6864] Re: watchdog fails to start pgpool-4.1.0

[Wolf Schwurack]

It seem that version 4.1.0 requires the second node to be started before acquired the delegate IP
After starting pgpool on the node 1 I’m seeing that watchdog successfully acquired the delegate IP on node 0

2020-02-11 10:45:26: pid 9928: LOG:  watchdog: escalation started
2020-02-11 10:45:33: pid 9928: LOG:  successfully acquired the delegate IP:"10.11.0.204"
2020-02-11 10:45:33: pid 9928: DETAIL:  'if_up_cmd' returned with success
2020-02-11 10:45:33: pid 9577: LOG:  watchdog escalation process with pid: 9928 exit with SUCCESS.

On previous versions watchdog would always acquire the delegate IP without the second node being started.

Subject: [pgpool-general: 6863] watchdog fails to start pgpool-4.1.0

I’m trying to get watchdog to start using pgpool-4.1.0 but fails to start. I have been using pgpool-4.0.5 with watchdog no issues.
Has something changed in version 4.1.0 for watchdog?
Hosts  - Ubuntu 18.0.4
PostgreSQL 11

I’ve been using pgpool for a long time on each new release I have always just done ./configure, make, make install

This is my start command

/usr/local/bin/pgpool -n -D -f /usr/local/etc/pgpool.conf > /var/log/pgpool/pgpool.log 2>&1 &
In pgpool.log it would always show if acquired the delegate ip
Version 4.0.5 start up watchdog
