Subject: pgpool2 HA + split brain
Date: Fri, 23 Nov 2018 10:14:54 +0000
Message-ID: <07b006680f7249b6a8fa437b9bc1121d@zuerich.ch> (raw)
Hi all,
I am thinking about a HA solution using pgpool2 + postgresql streaming replication.
I am afraid of a split brain scenario (two active primary databases).
In my opinion a split brain scenario should never happen when
a) I configure the postgresql clusters (pg_hba.conf) to accept only user connections coming from the pgpool2 server
b) pgpool2 initiates the failover
Do you agree or did I miss something?
Thanks,
Markus
