Filesystem management is among the most critical activities that you must perform to maintain a stable Linux system. In simple situations, after a successful installation, you may never have a problem or need to manage filesystem specifics. However, understanding how to configure and maintain Linux filesystems is essential to safely manage your system and to pass Exam 101. This section contains the following Objectives:
Objective 1: Create Partitions and Filesystems
This Objective states that an LPIC 1 candidate should be able to configure disk partitions and create filesystems on media such as hard disks. It also includes using various mkfs commands to set up partitions to filesystems such as ext2, ext3, reiserfs, vfat, and xfs. Weight: 3.
Objective 2: Maintain the Integrity of Filesystems
A candidate should be able to verify the intergrity of filesystems, monitor free space and inodes, and repair simple filesystem problems. This Objective includes the commands required to maintain a standard filesystem as well as the extra data associated with a journaling filesystem. Weight: 3.
Objective 3: Control Filesystem Mounting and Unmounting
Candidates should be able to manually mount and unmount filesystems, configure filesystem mounting on system boot, and configure user mountable removeable filesystems such as tape drives, floppies, and CDs. Weight: 3.
Objective 4: Managing Disk Quotas
