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
