Hey Ron,
Sorry I forgot I was going to post my plugins for this.
https://gist.github.com/2853872.
For this plugin, I create the volumes I want to use at amazon and add tags to them. When you tell the gluster cluster to be built, as each node is launched it searches the tags on your AWS volumes to see which it should mount locally. Each volume is given four tags: "brickNode", "type", "Name", and "volume". For a 4 node Gluster cluster, I would create four equally sized volumes. and then assign them like this:
brickNode: 0
type: "glusterbrick"
Name: "myVolume_0"
volume: "myVolume"
For the remaining 3 volumes, they get the same information except the brickNode and Name are incremented.
Assuming these volumes exist already when you launch the data cluster, the plugin will find them, attach them to the instance, format if necessary, and ultimately mount them and create the virtual Gluster volume among all the nodes.
There is probably a lot more detail that i'm leaving out at the moment, but let me know if you have any questions.
Dustin
