Hi,<br>
<br>
Oh! They are same. I just masked the values before pasting the
configuration files. Although, now that I think of it, its pretty
harmless. Here are the originals.<br>
<br>
controller node - <a class="moz-txt-link-freetext" href="http://paste.openstack.org/show/17513/">http://paste.openstack.org/show/17513/</a><br>
compute node - <a class="moz-txt-link-freetext" href="http://paste.openstack.org/show/17514/">http://paste.openstack.org/show/17514/</a><br>
volume node - <a class="moz-txt-link-freetext" href="http://paste.openstack.org/show/17515/">http://paste.openstack.org/show/17515/</a><br>
<br>
As per my understanding, I just need to figure out how the volume
node is identified. Thank you for replying.<br>
<br>
Regards,<br>
Shashank Sahni<br>

<br>
Thanks for the reply.<br>
<br>
Yes, I've gone through the document. Volume creation and
deletion are working
perfectly fine. When I run "iscsiadm -m discovery -t st -p
volume_node" on the compute node, I can see the volumes.
But somehow the
compute node is being misinformed about the volume node
after giving the attach
command.<br>
<br>
I'm not using iscsitarget as per that document.
Installation of nova-volume on
ubuntu precise automatically took care of it using tgt.<br>
<br>
Kind Regards,<br>

everyone,<br>
<br>
I'm trying to configure a multi-node installation.
Here is a brief overview.<br>
<br>
1) controller -
api+network+scheduler+novnc+glance+keystone (nova.conf
- <a href="http://paste.openstack.org/show/17470/"
target="_blank" moz-do-not-send="true">http://paste.openstack.org/show/17470/</a>)<br>
2) compute node (nova.conf - <a
href="http://paste.openstack.org/show/17469"
target="_blank" moz-do-not-send="true">http://paste.openstack.org/show/17469</a>)<br>
3) volume node(single)<br>
<br>
Compute and vnc are working fine. I'm able to create
and delete volumes. Iscsi
discovery from the compute nodes is working too. But
when I try to attach a
volume, the compute node tries to connect to the
controller node instead of
volume and hence crashes with the following error.<br>
<br>
