Managing File Systems and Disk Space

File systems in Red Hat Linux are organized in a hierarchy, beginning from root (/) and continuing downward in a structure of directories and subdirectories. As an administrator of a Red Hat Linux system, it is your duty to make sure that all the disk drives that represent your file system are available to the users of the computer. It is also your job to make sure there is enough disk space in the right places in the file system for users to store what they need.

File systems are organized differently in Linux than they are in MS Windows operating systems. Instead of drive letters (for example, A:, B:, C:) for each local disk, network file system, CD-ROM, or other type of storage medium, everything fits neatly into the directory structure. It is up to an administrator to create a mount point in the file system and then connect the disk to that point in the file system.

Cross-Referen Chapter 2 provides instructions for using Disk Druid to configure disk ce partitions. Chapter 4 describes how the Linux file system is organized.

The organization of your file system begins when you install Linux. Part of the installation process is to divide your hard disk (or disks) into partitions. Those partitions can then be assigned to: A part of the Linux file system, Swap space for Linux, or

Other file system types (perhaps containing other bootable operating systems) For our purposes, I want to focus on partitions that are used for the Linux file system. To see what partitions are currently set up on your hard disk, use the fdisk command as follows:
