title: Storage Capacity Issue/Errors Datastax Custom auto-cluster EC2 AMI
body: <p>I am trying to create a custom auto-clustering AMI to be used with the Datastax Enterprise 3.0 OpsCenter create cluster wizard.  </p>
  
  <p>I've tried at least two methods and keep ending up at the same place.  When I use the standard Datastax auto clustering (AC) AMI the size of the cluster is in the terabytes.  When I used my custom ami the size of the cluster is 40GB.  I am selecting 4 m1.extra large instances for each launch.</p>
  
  <p>Method 1: I took the standard datastax AC AMI made my modifications used the instruction set here: <a href="https://github.com/riptano/ComboAMI/blob/2.4/presetup/setup.md" rel="nofollow">https://github.com/riptano/ComboAMI/blob/2.4/presetup/setup.md</a>  (stopping at "# Setup credentials")
  I then used the following to bundle and upload to S3
  ec2-bundle-vol -k  -c  -u  -e  
  ec2-upload-bundle -b  -m  -a  -s 
  After that I used the EC2 Management console to register the AMI via the image.manifest.xml file.</p>
  
  <p>Method 2: I used the Ubuntu 12.04 LTS AMI instance made my modifications and used the same instruction set above.  </p>
  
  <p>Both methods gave me a 40GB cluster.  It looks like the custom AMIs do not set up the raid correctly or at all.  </p>
  
  <p>df -h for custom AMI</p>
