go to post Sylvain Guilbaud · Jul 9, 2024 The failover works fine as well if instead of a shutdown of the Linux server, I execute a "iris force iris".
go to post Sylvain Guilbaud · Jul 9, 2024 Hi @Kamal Suri below my results in a mirror env. After stopping the Primary Linux server, the IRIS instance on the Backup Linux server becomes Primary and forces the previous Primary IRIS to shutdown when it comes back (as expected).

go to post Sylvain Guilbaud · Jul 9, 2024 Hi @Kamal Suri I've not tested it in a mirror env. The restart of the primary Linux server should not increase (neither decrease) the time for the backup member to become primary.
go to post Sylvain Guilbaud · Jul 8, 2024 Hello @Moussa SAMB the problem comes from the expired license of version IRIS 2023.1.1 published in July 2023. I invite you to use a more recent version to overcome the problem.
go to post Sylvain Guilbaud · Jul 8, 2024 Good point. I've added it back to iris.service file in the article.
