Minecraft server ^{http://picraftbukkit.webs.com/pi-minecraft-server-how-to}

Install JAVA HardFloat

sudo wget http://www.java.net/download/jdk8/archive/b102/binaries/jdk-8-ea-b102-linux-arm-vfp-hflt-07_aug_2013.tar.gz
mkdir -p /opt
sudo tar zxvf (name of package) -C /opt
rm (name of package)
sudo /opt/jdk1.8.0/bin/java -version

Then download and extract the spigot version of the MineCraft server ans run the JAR. this is for 256 use 496 for 512 Pi. I takes time to generate the maps.

sudo wget http://ci.md-5.net/job/Spigot/lastStableBuild/artifact/Spigot-Server/target/spigot.jar
sudo /opt/jdk1.8.0/bin/java -Xms128M -Xmx256M -jar /home/pi/spigot.jar nogui

Clustering of minecraft ^{http://www.minecraftwiki.net/wiki/Tutorials/High-Availability_Cluster}

Setting clustering up is a very long and involved process but essentially you need to install DRBD which is is a block device replication daemon. Pacemaker is the utility that will manage all the services and ensure they stay running.

Basically each data store is replicated on each Pi so the data us synchronised on all the Pi's. Each Pi runs its own version of the minecraft server so if any Pi goes down the server will keep running.
