7.3. GFS

SSI clustering currently depends on the Global File System (GFS) to provide a single root. The open-source version of GFS is maintained by the OpenGFS project. They also have a SourceForge project summary page.

Right now, GFS requires either a DMEP-equipped shared drive or a lock server outside the cluster. The lock server is the only software solution for coordinating disk access, and it is not truly HA. There are plans to make OpenGFS support IBM's Distributed Lock Manager (DLM), which would distribute the lock server's responsibilities across all the nodes in the cluster. If any node fails, the locks it managed would failover to other nodes. This would be a true HA software solution for coordinating disk access.
