Hi Dan,<br>
There is a command that will create volumes for you:<br>
starcluster createvolume 30 us-east-1b<br>
<br>
Have you tried that? Starcluster expects a partition, thats
probably why its failing. I'd use the command unless I had some
specific reason I couldn't. I was unaware of it for about 3 months
though :)<br>

<div>Was there something else I need to do? How do I put a named
partition such as /dev/sdz1 on the volume? </div>
<div>BTW, I don't want to partition the volume, but I want to use
the whole thing.</div>
<div><br>
</div>
<div>I have set up volumes before using this procedure and not run
into any problems.</div>
<div><br>
</div>
<div>BTW, after I ssh into the master, and do fdisk /dev/sdz, I
see this:</div>
<div>
<div># fdisk /dev/sdz</div>
<div>Device contains neither a valid DOS partition table, nor

<div>After that, of course, the previous content won't be
recoverable.</div>
<div><br>
</div>
<div><br>
</div>
<div>The number of cylinders for this disk is set to 3916.</div>
<div>There is nothing wrong with that, but this is larger than
1024,</div>
<div>and could in certain setups cause problems with:</div>
<div>1) software that runs at boot time (e.g., old versions of
LILO)</div>
<div>2) booting and partitioning software from other OSs</div>
<div> (e.g., DOS FDISK, OS/2 FDISK)</div>
<div>Warning: invalid flag 0x0000 of partition table 4 will be

<div><br>
</div>
</div>
<div>Not sure if that is relevant or not.</div>
<div><br>
</div>
<div>Please let me know how I am supposed to configure the volume.
Thanks</div>
