Hello. Is there someone that already tried using 3 or more master nodes via Mariadb-galera cluster? My idea would be to pair that with GlusterFS to replicate the websites data (instead of asynchronous Unison). That would allow easy expansion of the available storage space by just adding storage nodes (no need to replicate ISPC installation). The remaining problem is the IP migration for continuous access to the vhosts.... Comments? Already in Till's plans?
