I see. 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.

Thanx for your feedback

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.

Best Regards,
Strahil Nikolov
