Chapter 6: Logical Volume Concepts


This chapter explains the concepts of logical volumes. The use of logical volumes allows one filesystem to spread across multiple disk partitions.

Two types of logical volumes, lv and XLV, are supported by IRIX, included in standard system software, and described in this chapter. Support for lv logical volumes will be removed from IRIX following IRIX Release 6.2. The procedure for converting from lv logical volumes to XLV logical volumes is described in the section "Converting lv Logical Volumes to XLV Logical Volumes" in Chapter 7.

The major sections in this chapter are:

Administration procedures for XLV logical volumes are described in Chapter 7, "Creating and Administering XLV Logical Volumes," and administration procedures for lv logical volumes are described in Chapter 8, "Creating and Administering lv Logical Volumes."
