StarCluster Development VPC-Starclusters - possible bug relating to "Tag Value exceeds 255 characters"....

From: Jennifer Staab <no email>

I have had limited success getting Starcluster to successfully launch a
cluster with EC2-VPC nodes under the development version (0.9999). Using a
certain AMI I can easily launch a Starcluster cluster with EC2-VPC nodes,
but using a different AMI it fails to launch. I do set the config
variables "VPC_ID" and "SUBNET_ID" and the only difference between the two
cluster templates is the AMI that is used.

Both AMIs used successfully launch a Starcluster cluster with EC2-classic
nodes. The only noted difference between the AMIs is that the one that
successfully launches a Starcluster cluster with VPC-EC2 nodes is a private
AMI that is "shared" with the account that I am running my VPC within. The
AMI that doesn't work with Starcluster-VPC is one that is private AMI
"owned" by the account I am running my VPC within.

I believe the error I am getting has something to do with the Tags,
specifically the "_at_sc-core" tag's value being beyond 255 characters, but I
could be wrong. Below I have included an example of the successful launch,
the failed launch (including error message), and the listed clusters after
both commands.

Any suggestions on how to address this issue would be greatly appreciated.

Thanks in advance for the help,

-Jennifer

The cluster is now ready to use. To login to the master node
as root, run:

    $ starcluster sshmaster vpcA

If you're having issues with the cluster you can reboot the
instances and completely reconfigure the cluster from
scratch using:

    $ starcluster restart vpcA

When you're finished using the cluster and wish to terminate
it and stop paying for service:

    $ starcluster terminate vpcA

Alternatively, if the cluster uses EBS instances, you can
use the 'stop' command to shutdown all nodes and put them
into a 'stopped' state preserving the EBS volumes backing
the nodes:

    $ starcluster stop vpcA

WARNING: Any data stored in ephemeral storage (usually /mnt)
will be lost!

You can activate a 'stopped' cluster by passing the -x
option to the 'start' command:

    $ starcluster start -x vpcA

This will start all 'stopped' nodes and reconfigure the
cluster.
