Introduction

There is now a kernel module (aoe), tools (aoetools) and server software (vblade) which allows anyone to set up an ATA over Ethernet storage network... it is very easy to do in Ubuntu. This software was available in Dapper 6.06 LTS, but has also been tested in Feisty (beta). WARNING: These commands need to be run with root privileges (sudo -i). Do this at your own risk. WARNING: Don't mount the target from more than one client or filesystem corruption will occur. To do this something like GFS is needed.

Required Packages

With the Universe repository enabled.. On the Ubuntu host that you wish to be the disk server:

(server)# apt-get install vblade

On the Ubuntu host that you wish to mount the disk on:

(client)# apt-get install aoetools

To set the interface up

It's important to note that no IP address is needed to get this working.

# ip link set eth0 up

To create an AoE device

To test that everything is working correctly, we created and used a 1 Mbyte file (vblade0). Any other block device or file could be used. On the server:

(server)# dd if=/dev/zero of=vblade0 count=1 bs=1M
(server)# vblade 1 1 eth0 vblade0
ioctl returned 0
1048576 bytes
pid 25000: e1.1, 2048 sectors

The deamon ('vbladed') could be used instead of 'vblade', which detaches the process from the console and send log messages to the system logs.

Using AoE

The 'aoe' module should already be automatically loaded when the 'aoetools' package is installed. If this hasn't occured, insert the module into the linux kernel.

(client)# modprobe aoe

optionally the list of interfaces can be specified while loading the module

(client)# modprobe aoe aoe_iflist="eth0 eth1"

This can automatically be performed at startup, by entering a line into the /etc/modules file. Create the 'etherd' directory

(client)# mkdir /dev/etherd
(client)# aoe-interfaces eth0
(client)# aoe-discover
(client)# aoe-stat
e1.1         0.001GB   eth0 up 

The block device is then located in /dev/etherd/e1.1 and can be treated like any other block device. Create a filesystem:

(client)# mke2fs /dev/etherd/e1.1

Create a mount point and mount the file system:

(client)# mkdir /mnt/e1.1
(client)# mount /dev/etherd/e1.1 /mnt/e1.1

This can be made to automatically mount on reboot, by entering a configuration line in /etc/fstab (untested).
