Step 16. Create a Golden Image of a Compute Node from the Management Server

Background

A system image is an archive of a computer’s file system. Capturing the file system

of a computer captures the basic state of a computer system. An image does not

generally include all files however. By default, /tmp and other temporary files,

network directories, and host specific configuration files are not included.

A system image may be referred to as a Golden Image or a recovery image. The

different names used to refer to the image reflect the different reasons for creating

it. Administrators may create a “recovery” image of a node in the event that the

node experiences hardware failure or the file system is accidentally removed or

corrupted. Administrators may also create a “Golden” Image for the purpose of

installing it on other nodes to insure that each node in their cluster is configured

exactly the way they want.

Overview

• Clean up anything on the system that shouldn’t be in the image.

• Ensure that the system isn’t being used.

• Run sysimage_create to create the Golden Image.

Details

• Log on to the Compute Node to be archived.

• Perform general file system cleanup and maintenance. For example, it may be

desirable to search for and remove core files.

From the Management Server:

• Ensure that the system is not being used. It is advisable that the system stop

accepting new LSF jobs while the archive is being made.
