3.5.1 Matrix Server Administration Guide

Configure Dynamic Volumes

Matrix Server includes a Matrix Volume Manager that you can use to

create, extend, recreate, or delete dynamic volumes. Dynamic volumes

allow large filesystems to span multiple disks, LUNs, or storage arrays.

Overview

Basic and Dynamic Volumes

Volumes are used to store PSFS filesystems. There are two types of

volumes: dynamic and basic.

Dynamic volumes are created by the Matrix Volume Manager. They can

include one or more disks, disk partitions, or LUNs that have been

imported into the matrix. These entities are called subdevices. A single

PSFS filesystem can be placed on each dynamic volume. Additional

subdevices can be added to a dynamic volume as necessary, and the

filesystem on the volume can also be extended.

A basic volume consists of a single disk, disk partition, or LUN that has

been imported into the matrix. A PSFS filesystem is then created directly

on the disk, partition, or LUN. Basic volumes can be converted to

dynamic volumes.
