Abstract

So far, you’ve installed CentOS, learned a few key commands, and configured a few basic services. Now, we’re going to look at adding additional resilience and reliability to your system. We’ll do this by improving how hard drives and partitions are handled. We’ll be looking specifically at two technologies: RAID (Redundant Array of Inexpensive Disks) and the LVM (Logical Volume Manager). The first provides redundancy (usually anyway—you’ll learn more about this a little later in this chapter when we talk about RAID levels), and the second makes partition management (such as resizing or creating a single partition across two disks) very straightforward.
