View Stripeset Information

To see the contents of a stripeset, run mpdump.exe with no options from

the Command Prompt. The command is in the directory Program

Files\Polyserve\MatrixServer\bin on the drive where you installed Matrix

Server. Following is some sample output.

Current Product MP Version: 2

The volume information appears near the end of the output, in the section

labeled “Membership Partition Volume Database.” The information

includes the stripe size and the subdevices making up each stripeset.

Extend a Dynamic Volume

The Extend Volume option allows you to add subdevices to an existing

dynamic volume. When you extend the volume on which a filesystem is

mounted, you can optionally increase the size of the filesystem to fill the

size of the volume.

NOTE: The subdevices used for a striped dynamic volume are called a

stripeset. When a striped dynamic volume is extended, the new

subdevices form another stripeset. The original stripeset is filled

first; then the new stripeset is filled. If you want the entire

dynamic volume to be in the same stripeset, you will need to

recreate the volume.
