Hi guys,
  I'm having 2 major issues getting our recipes working with EC2. The first is it appears the AWS issue works only with the east region, which we are not using.  I've create a patch and outlined the issue here.


Second, I'm not a Ruby dev, and I'm having some issues with creating a RAID 0 EBS system.  I'm using 10 drives for my system.  I have a simple loop that iterates from 1 to 10 and attempts to create the ebs for given devices.  The loop executes without actually creating anything, and I receive no errors.  Here is the method within my recipe

def createRaid(mnt_point, raid_dev, disk_dev, raid_size)
  aws = data_bag_item("deployment", "aws")
  ami = node[:ec2][:ami_id]
  #the data bag
  bag_id = "#{node[:cassandra][:cluster_name]}_#{ami}"
  item = {
        "id" => bag_id,
        "cass_cluster" => node[:cassandra][:cluster_name]
  mount_meta = {"raid_dev" => raid_dev}
  #Create the mount point data bag 
  devices = {}
  #For each volume add information to the mount metadata 
  for i in 1..10 do
    Chef::Log.info("Logging index #{i}")
    disk_dev_path = "#{disk_dev}#{i}"

    Chef::Log.info("creating ebs volume for device #{disk_dev_path}")
    aws_ebs_volume "#{disk_dev_path}" do
      aws_access_key aws['accesskey']
      aws_secret_access_key aws['secretkey']
      size raid_size/10
      #name disk_dev
      device disk_dev_path
      action [:create]
      provider "aws_ebs_volume"  
    #Get the ebs information and put it in a data bag
  #Sleep until all disks are created

  Chef::Log.info("create complete")
  #Assemble all the data bag meta data
  mount_meta["devices"] = devices
  item[mnt_point] = mount_meta
  databag_item = Chef::DataBagItem.new
  databag_item.raw_data = item
  Chef::Log.info("Updated data bag")

Any help would be greatly appreciated. I've been spinning my wheels for 2 days, and I'm not getting any responses on IRC.
