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:

What you need

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

Hostnames and IPs

Here you see two tables with the used IP-addresses on both hosts.

production network

If a client should connect to the Gluster-cluster an IP-address from the production network is used.

Hostname IP-address

Heartbeat network

The heartbeat network is only for the communication between the Gluster-nodes

Hostname IP-address

The mountpoints

you need two mountpoints, one for the physical brick and one for the volume.

Mountpoint What to mount
/gluster The brick on each node
/glusterfs For the volume on each node

The first step will be, setting up the replicated Gluster-Volume with two nodes.
