SOLARIS 9 EXAM OBJECTIVES COVERED IN THIS CHAPTER:
Explain when and how to add and remove swap space.
Given a crash dump scenario, change the crash dump and core file configuration.
Identify the appropriate commands and procedures to manage files; list, start, and stop daemons; and manage utilities on NFS servers and clients.
Explain how to enable NFS server logging and how to configure nfslogd behavior.
Given a problem scenario and resulting NFS error message, infer causes and select an appropriate course of action to resolve the problem.
Explain how to configure AutoFS using automount maps.
Chapter 7, "File System Management," introduced the three classifications of file systems in Solaris: disk-based, pseudo (or virtual), and distributed. Chapter 7 also went on to explain in detail how disk-based file systems work. This chapter covers the other two types of file systems: virtual file systems and distributed (or network) file systems.
Virtual file systems are different from disk-based file systems in that most virtual file systems are created in memory, not on disk space. And while disk-based file systems are primarily used to store files, virtual file systems provide some sort of auxiliary service, such as improving the speed of system performance.
When talking about a distributed file system in Solaris, the topic of the conversation must be the Network File System (NFS). NFS enables disk-based file systems to be easily shared across a network. Although managing NFS can be complex, NFS is not too difficult to manage if you think of it as a network extension to disk-based file systems such as UFS.
