LMV介绍

“Logical volume management provides a higher-level view of the disk storage on a computer system than the traditional view of disks and partitions. This gives the system administrator much more flexibility in allocating storage to applications and users. ”

This is an attempt to collect everything needed to know to get LVM up and running. The entire process of getting, compiling, installing, and setting up LVM will be covered. Pointers to LVM configurations that have been tested with will also be included. This version of the HowTo is for LVM 2 with device-mapper and LVM 1.0.8.
