# GFS2 Pools Overview

GFS2 is a shared-disk cluster file system that allows multiple nodes in a cluster to access the same storage at the block level. Adding GFS2 datastores to an HVM Cluster enables live migration and live failover of running VMs.

Administrators only need to present the disks to the HVM Hosts and make a few specific configurations. HPE Morpheus VM Essentials handles everything else, including mounting datastores and enabling multipathing.
