Red Hat GFS (Global File System) — Provides a cluster file system for use with Red Hat Cluster Suite. GFS allows multiple nodes to share storage at a block level as if the storage were connected locally to each cluster node. • Cluster Logical Volume Manager (CLVM) — Provides volume management of cluster storage. • Global Network Block Device (GNBD) — An ancillary component of GFS that exports block-level storage to Ethernet. This is an economical way to make block-level storage available to Red Hat GFS. For a lower level summary of Red Hat Cluster Suite components and optional software, refer to Chapter 2, Red Hat Cluster Suite Component Summary. Red Hat Cluster Suite Introduction 3
