<br></blockquote></div>Hi Livemoon,<div><br></div><div>It looks like your data-path to your volumes is configured incorrectly, it appears to be pointing to the source cinder/volume.py file but this is actually supposed to be the path to your actual LVM (ie /opt/stack/data/cinder/volumes/) and yes it needs to be added to your /etc/tgt/conf.d/cinder.conf file.</div>
<div><br></div><div>For example, in devstack we use the default path I mentioned above, and create the persistence file cinder.conf in /etc/tgt/conf.d. Here's what that looks like:</div><blockquote style="margin:0 0 0 40px;border:none;padding:0px">
<div>vagrant@precise:/etc/tgt$ cat /etc/tgt/conf.d/cinder.conf </div><div>include /opt/stack/data/cinder/volumes/*</div><div>vagrant@precise:/etc/tgt$ </div></blockquote><div><br></div><div>Let me know if this isn't enough to get things sorted and we can work through a bit more.</div>
<div><br></div><div>Thanks,</div><div>John</div>
