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.
