Lesson 1

Introduction to administering Local Filesystems and Filesystem Administration

Filesystems play a pivotal role in your Linux system. Their configuration, performance, and security affect your data's availability and reliability. Properly configured and tuned, your Linux filesystem will provide users with highly available and secure data for years to come. However, if not configured correctly, your filesystems could lose data, become a target of network hackers, or simply not perform optimally.
In this module, you will configure and optimize your Linux filesystems using the ext2fs tools. You will also weigh the advantages of using an automounter[1] to configure local filesystems against the inherent security risks involved in automounting. Finally, you will learn about tools that monitor and resolve filesystem problems.

Module objectives

After completing this module you will be able to
  1. Use the mke2fs command to adjust the filesystem's block size
  2. Use tune2fs, dumpefs, and debugfs to optimize and configure the ext2 filesystem
  3. Discuss the use of the automounter
  4. Set up the automounter
  5. Use rdist to synchronize files between the local host and a remote machine
  6. Use rsync to synchronize files between the local host and a remote machine
  7. List the commands for monitoring filesystem usage
  8. Resolve filesystem problems
The next lesson discusses optimizing and configuring the ext2 filesystem.

[1] Automounter: An automounter is a program that automatically mounts filesystems when those filesystems are first accessed.
