The AN!Cluster unnamed assassin.

About

Node Assassin is an open hardware, open source cluster fence device.

It is 100% compatible with the RedHat/CentOS cluster management suite.

Download

All downloads include all files needed to build your own Node Assassin from commodity parts.

Downloads
Type Link Size Description
Source node_assassin-1.1.4-1.tar.gz 18 MiB Contains all files and programs needed to build a Node Assassin, load its NAOS and install its fence agent. Simply run the 'install' script from the root of the directory created by extracting the tarball.
 Minimal  node_assassin-1.1.4_minimal.tar.gz 37 KiB Same as the full source, but without the build images and files and does not have the Arduino IDE or BSchV3 programs. Substantially smaller download.

Node Assassin

Apr. 03, 2010: The current Node Assassin; v1.1.4 Prototype A.

There are four major sections:

The NA Fence Agent

This is the FenceAgentAPI compatible fence agent for Node Assassin devices. It is a perl program consisting of three files;

  • /sbin/fence_na - The core agent called by the fenced daemon.
  • /etc/fence_na/fence_na.lib - The fence agent library.
  • /etc/fence_na/fence_na.conf - The configuration file for your Node Assassin(s).

All the details, including the source code and installer, can be found in the following article:

NAOS: The Node Assassin Operating System

NAOS is the Arduino-based sketch that operates the Node Assassin. You will need to edit the source file naos_v1.1.4.4.c to match your environment and then load it into your Node Assassin. Everything you need to know can be found in the link below:

Building Your Own Node Assassin

At this time, the commercial, pre-built Node Assassin is still in development. In order to get a Node Assassin now, you will need to build your own.

If you live in a big city, then your local electronics hobby shop should have everything you need. If you don't, then you can either order the parts from an online supplier or, if you wish, you can buy a kit with everything you need from us.

TNAP; The Node Assassin Protocol

Node Assassins are accessed and controlled over telnet using a custom protocol called TNAP. For day-to-day clustering, you do not need to worry about the protocol as the fence agent handles the communication for you behind the scenes. If you would like to know the details though, or would like to help improving the protocol, all the details are in the following article.

Getting Help

To get help with using or building your Node Assassin, please pop over to the AN!BBS. It's new, and looks pretty quiet, but I will be watching it closely while things get off the ground. Please don't hesitate to post and I will do my best to help out however I can.
