18.1. 概述

In FreeBSD, the GEOM framework permits access and control to classes, such as Master Boot Records and BSD labels, through the use of providers, or the disk devices in /dev. By supporting various software RAID configurations, GEOM transparently provides access to the operating system and operating system utilities.

This chapter covers the use of disks under the GEOM framework in FreeBSD. This includes the major RAID control utilities which use the framework for configuration. This chapter is not a definitive guide to RAID configurations and only GEOM-supported RAID classifications are discussed.

讀完這章,您將了解︰

  • What type of RAID support is available through GEOM.

  • How to use the base utilities to configure, maintain, and manipulate the various RAID levels.

  • How to mirror, stripe, encrypt, and remotely connect disk devices through GEOM.

  • How to troubleshoot disks attached to the GEOM framework.
