[StarCluster] cannot mount directories at work nodes.

[Jianwu Wang]

Hi All,

     I'm new to StartCluster. Yet my current experience tells me it is 
wonderful toolkit. Thanks for sharing it.

     I built a new AMI based on the newest starCluster AMI : 
ami-a19e71c8 (x86_64). I'm trying to start a SGE cluster using this ami 
and my ebs volume. The version of starCluster is version 0.91.2. But I 
always cannot mount /home and other directories at worknodes. The 
detailed info is as below. Please help, thank!

kepler:bin jianwu$ ./starcluster start smallcluster

The cluster has been started and configured.

Login to the master node as root by running:

$ starcluster sshmaster smallcluster

or manually as sgeadmin:

$ ssh -i /Users/jianwu/.starcluster/jianwu-ami-keypair.rsa 
sgeadmin at ec2-75-101-211-51.compute-1.amazonaws.com

When you are finished using the cluster, run:

$ starcluster stop smallcluster

to shutdown the cluster and stop paying for service
