<span lang="EN-US"> </span></p><p class="MsoNormal"><span lang="EN-US">I have successfully installed 0.93.3 on Windows and associated it with my AWS login. I can create clusters and I have used the documented way of created an EBS store for use by my application. </span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p><p class="MsoNormal"><span lang="EN-US">My problem is that none of the instances in the cluster will mount the EBS and the master complains about it having more than one partition. It was created according to the method here: <a href="http://web.mit.edu/star/cluster/docs/latest/manual/volumes.html#create-and-format-a-new-ebs-volume">http://web.mit.edu/star/cluster/docs/latest/manual/volumes.html#create-and-format-a-new-ebs-volume</a> – and to the best of my knowledge correctly so. I think I am doing all the things I am supposed to do, but obviously I am missing something. The configuration file is attached but it does not seem to be causing StarCluster any problems.</span></p>
