AOE is quite simple. on ubuntu you can build a target like this
have a spare drive/partition/lvm!
sudo apt-get install vblade
vblade 0 0 eth0 /dev/sdc
thats it! now you are exporting a device on shelf 0, slot 0 (vblade 0 0)
on another machine
sudo apt-get install aoetools
modprobe aoe
you should now see /dev/etherd/e0.0 (this is the shelf 0, slot 0 drive from
the other machine)
done!
a 'client' can see any aoe device on the network, without even having an IP
address. IP is not used at all on aoe.
now on the 'client' machine, you can
"mkfs.ext3 /dev/etherd/e0.0 && mkdir /mnt/e0.0 && mount /dev/etherd/e0.0
/mnt/e0.0"
or better yet, add it to your raid array with mdadm.
