-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.
