3.6.0 Matrix Server 3.6.0 Administration Guide (5697-7081, December 2007)

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.

Dynamic volumes can be deported from the matrix and later imported

back into the original matrix or into another matrix.

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 disk partitions 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 partition that has been imported

into the matrix. A PSFS filesystem is then created directly on the disk.

Basic volumes can be converted to dynamic volumes.
