Chapter 3: Filesystem Concepts
This chapter explains some important concepts about hard disk filesystems, the structure by which files and directories are organized in the IRIX system. The chapter describes the primary types of IRIX filesystems, the older Extent File System (EFS) and the newer XFS filesystem, and other disk filesystems. It explains concepts that are important to filesystem administration such as IRIX directory organization, filesystem features, filesystem types, creating filesystems, mounting and unmounting filesystems, and checking filesystems for consistency.
The major sections in this chapter are:
Even if you are familiar with the basic concepts of UNIX filesystems, you should read through the following sections. The IRIX EFS and XFS filesystems are slightly different internally from other UNIX filesystems and have slightly different administration commands and procedures.
Filesystem administration procedures are described in Chapter 4, "Creating and Growing Filesystems," and Chapter 5, "Maintaining Filesystems."
For information about floppy and CD-ROM filesystems, see the guide IRIX Admin: Peripheral Devices.
