GlusterFS is _definitely_ easier to set up than dual-Primary DRBD with OCFS2, and also much harder to break. Whether GlusterFS is easier to set up and run compared to single-Primary DRBD and NFS, however, is up to you to decide. If you need more than two replicas then definitely so, but for the 2-replica use case it's about even. > And you use the haproxy/stunnel to monitor availability of the nodes (apache) > ? > > @Florian > I would use mysql-cluster for the database rather than file based replication. "MySQL Cluster" as in NDB? Or Galera replication? Or MySQL replication in dual-master mode (*shudder*)? Or MySQL on DRBD?
