We've got another storage server in our cluster. The storage servers are also the DB servers (to keep all the data together for backups). Now that we've got two DB servers, I thought that I could go with MariaDB Galera Cluster to have an active-active DB cluster. But before I actually did anything, I remembered that ISPConfig itself uses a MySQL database for its own local configuration. So the problem is that if I were to set up such a DB cluster, then how would I maintain the ISPConfig configuration correctly? If I just have the new storage server ("storage1") blindly copy the old storage server ("storage0"), then wouldn't this also copy over the "dbispconfig" database too and basically nuke the ISPConfig configuration? Has anyone dealt with this sort of thing and knows what to do?
