Hello! We have a setup that looks like this: 2 webservers (Ubuntu 18, apache2, gluster) 2 db servers (mariadb, galera) 2 haproxy servers 1 VIP Using ISPconfig for our sites and GlusterFS for files and Galera for DB. Question is we have setup web-01 and web-02 in ISPConfig and specified that web-02 is a mirror of web-01. Creating a new site works fine and it goes in on both servers. When we close web-01 we get Error 503 on the website we are testing with. The one thing that is a bit special here is that we are only using Gluster for our files folder the actual php site is just in /var/www. files folder is symlinked to gluster. Any ideas what to do here? Haproxy seems to be working. I feel it's something with our ISPconfig setup that is wrong.
