Disk space management

Mounting and unmounting the file system

System performance management

Tip for Beginners

Read the initial part of this chapter so that you understand what filesystems are and how to determine how much disk space is available in each one. Skip the rest of the chapter. You will probably not have to mount or unmount any filesystems as this is usually done automatically. lost+found, quotas, and the remaining topics are for more advanced users.
