Learn to: Allocate filesystems and swap space to separate partitions or disksTailor the design to the intended use of the systemEnsure the system can be bootedUnderstand the basic features of Logical Volume Manager (LVM) This article helps you prepare for Objective 102.1 in Topic 102 of the Linux Professional Institute's Junior Level Administration (LPIC-1) exam 101.
The objective has a weight of 2. Note: This article deals mostly with planning the layout. For the implementation steps, see the articles for Topic 104 (described in our series roadmap). Note: This article includes material for the LPI Exam 101: Objective Changes as of July 2, 2012. Prerequisites To get the most from the articles in this series, you should have a basic knowledge of Linux and a working Linux system on which you can practice the commands covered in this article.
