Chapter 11 The Logical Volume Manager

   

The logical volume manager (LVM) is a disk management subsystem. It provides a layer of abstraction between the physical disks and the disk I/O system. This chapter looks at how LVM combines physical disks into volume groups, divides those volume groups into logical disk volumes, and provides mirroring for data redundancy. The structures used within the kernel as well as the on-disk structures are discussed.
