Fundamentals

GlusterFS is a free and open source scalable filesystem it can be used for cloud storage or to store data in a local network. It can be used to set up an active-active filesystem cluster with failover and loadbalancing via DNS-round robin. Together with CTDB it is possible to build a fileserver for a network with the following advantages:

  • Expandable without downtime
  • Mount Gluster volumes via the network
  • Posix ACL support
  • Different configurations possible (depending of your needs)
  • Self-healing
  • Support of snapshots if LVM2 thinly provisioned is used for the bricks

The different configurations available are:

  • Replicated Volume
  • Distributed Volume
  • Striped Volume
  • Replicated-Distributed Volume
  • Dispersed Volume

To read more about the different configurations see:


This article is part of CTDB-setup so it just shows how to setup a replicated volume to be used with CTDB. The setup will be a two node replicated volume with 2GB diskspace, so it will be easy to reproduce the setup.

What you need

  • Two hosts with two network cards
  • An empty partition of 2GB to create the volume on each host
  • Four IP addresses from your production network
  • Two IP addresses for the heartbeat network
  • The GlusterFS packages version 7.x
  • Samba packages 4.11
