What is Linux Cluster Manager (LCM)

Linux Cluster Manager is a graphical tool for managing multiple Linux systems from a central location.  Meant primarily for Beowulf style clusters, it has many useful features for general system administration and even some non Linux specific possibilities like block level imaging.

Imaging with LCM is quick and easy as each node has its IP and hostname changed ready for boot as an independant node preloaded with all of your applications.  Using a file based image, items can be changed such as the target device, the file system capacity, or even the file system type.  Imagine requiring a new partition on boot disks already filled across hundreds of machines.  It is a simple property change, re-image the node(s), and you are ready to go.

Features

• Easy to use GUI for all operations

• Real time status information for all nodes
  

• Connect to individual nodes via a user specified protocol (ssh, rsh, rlogin ,etc)

• Report on running processes across the cluster

Imaging Features

• Imaged nodes have IP and hostname information changed automatically, just image and boot

• Block level system imaging (can be used for any x86 based operating system)

• File level system imaging

• Wake on LAN for imaging

• Preconfigured for PXE boot of clients

• Images can be customized - target device changed, file system size, file system type
  

Monitor Features

• Real time status monitoring for all nodes, CPU and Network

• Scrolling, scalable graphs

• View all nodes or a subset you are interested in

Scripting Features

• Run scripts across the cluster or on select nodes without a client agent

• Connects via a user selected protocol with secure authentication

• Command line or GUI interface

• Can be incorporated into external scripts
