GFS2 Best Practices

The Global File System 2 (GFS2) file system allows several computers (“nodes”) in a cluster to cooperatively share the same storage. To achieve this cooperation and maintain data consistency between the nodes, the nodes employ a cluster-wide locking scheme for file-system resources. This locking scheme uses communication protocols such as TCP/IP to exchange locking information.

You can improve performance by following best practices as described in this document, including recommendations for creating, using, and maintaining a GFS2 file system.
