Hi Alex, I can share that oVirt is using Gluster as a HCI solution and many people are hosting DBs in their Virtual Machines.Yet, oVirt bypasses any file system caches and uses Direct I/O in order to ensure consistency. As you will be using pacemaker, drbd is a viable solution that can be controlled easily.

Since I will not have only mariadb, then I have to setup the same replication for postgresql and later influxdb, which adds into the complexity. For cluster management I will be using pacemaker/corosync.
