GlusterFS is a distributed filesystem that is scalable and highly available. You can configure GlusterFS with a few modes, such as replicated, distributed, and dispersed. Each comes with its benefit and can be configured based on your workload or requirement.

You can create high availability storage with GlusterFS on two or more common off-the-shelf server hardware. It could be easily be configured on Linux distributions such as CentOS / Red Hat and Ubuntu.
