Hi all,<div><br></div><div>I created a 30GB EBS volume, formatted it with the ext3 filesystem, and detached it.</div><div><br></div><div>Then I set my cluster config to use this volume.</div><div><br></div><div>VOLUMES = sharedhome</div>
<div>...</div><div><div>[volume sharedhome]</div><div>VOLUME_ID = vol-70e6f719</div><div>MOUNT_PATH = /home</div></div><div><br></div><div>I start my cluster and see the following output:</div><div><br></div><div><div>>>> Waiting for cluster to start.../>>> The master node is <a href="http://ec2-184-73-92-19.compute-1.amazonaws.com">ec2-184-73-92-19.compute-1.amazonaws.com</a></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 Sun, SGI or OSF disklabel</div><div>Building a new DOS disklabel with disk identifier 0x5cde0278.</div><div>Changes will remain in memory only, until you decide to write them.</div>
<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 corrected by w(rite)</div><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>
