I just setup a galera databasewith 3 pollers and all three running galera.
Database: incorrect column (users/created_at)
Run the following SQL statements to fix it
datetime timestamp NOT NULL DEFAULT ‘1970-01-02 00:00:00’ ;
created_at timestamp NOT NULL DEFAULT ‘1970-01-02 00:00:01’ ;
If I run the option to fix it, the problem shifts to the other system. The fix syntax is the same across all three systems. They all have the same timezones set for php, mariadb, and system.
