StarCluster not mounting EBS volume correctly

Hi all,

I created a 30GB EBS volume, formatted it with the ext3 filesystem, and
detached it.

Then I set my cluster config to use this volume.

VOLUMES = sharedhome
[volume sharedhome]
VOLUME_ID = vol-70e6f719
MOUNT_PATH = /home

I start my cluster and see the following output:

>>> Waiting for cluster to start.../>>> The master node is
>>> Attaching volume vol-70e6f719 to master node on /dev/sdz ...

>>> Setting up the cluster...
>>> Mounting EBS volume vol-70e6f719 on /home... - WARNING - specified key does not end in either rsa or dsa,
trying both
>>> Using private key /Users/dtenenba/.ec2/bioc-keypair.pem (rsa) - WARNING - Cannot find partition /dev/sdz1 on volume
vol-70e6f719 - WARNING - Not mounting vol-70e6f719 on /home - WARNING - This either means that the volume has not
beenpartitioned or that the partition specifieddoes not exist on the volume

I formatted my volume according to these instructions:
Was there something else I need to do? How do I put a named partition such
as /dev/sdz1 on the volume?
BTW, I don't want to partition the volume, but I want to use the whole

I have set up volumes before using this procedure and not run into any

BTW, after I ssh into the master, and do fdisk /dev/sdz, I see this:
# fdisk /dev/sdz
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF
Building a new DOS disklabel with disk identifier 0x5cde0278.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

The number of cylinders for this disk is set to 3916.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by

Not sure if that is relevant or not.

Please let me know how I am supposed to configure the volume. Thanks
