Quick Start Guide
Here are the bare minimum steps you need to get Gluster up and running. If this is your first time setting things up, it is recommended that you choose your desired setup method i.e. AWS, virtual machines or baremetal after step four, adding an entry to fstab. If you want to get right to it (and don't need more information), the steps below are all you need to get started.
You will need to have at least two nodes with a 64 bit OS and a working network connection. At least one gig of RAM is the bare minimum recommended for testing, and you will want at least 8GB in any system you plan on doing any real work on. A single cpu is fine for testing, as long as it is 64 bit.
Partition, Format and mount the bricks
Assuming you have a brick at /dev/sdb:
fdisk /dev/sdb and create a single partition
Format the partition
mkfs.xfs -i size=512 /dev/sdb1
Mount the partition as a Gluster "brick"
mkdir -p /export/sdb1 && mount /dev/sdb1 /export/sdb1 && mkdir -p /export/sdb1/brick
Add an entry to /etc/fstab
echo "/dev/sdb1 /export/sdb1 xfs defaults 0 0" >> /etc/fstab
Install Gluster packages on both nodes
rpm -Uvh http://download.gluster.com/pub/gluster/glusterfs/LATEST/Fedora/glusterfs{,-server,-fuse,-geo-replication}-3.3.1-1.fc16.x86_64.rpm
Note: This example assumes Fedora 16
Run the gluster peer probe command
Note: From one node to the other nodes (do not peer probe the first node)
gluster peer probe <ip or hostname of second host>
Configure your Gluster volume
gluster volume create testvol rep 2 transport tcp node01:/export/sdb1/brick node02:/export/sdb1/brick
Test using the volume
mkdir /mnt/gluster; mount -t glusterfs node01:/testvol; cp -r /var/log /mnt/gluster
