Yeah you are right. I checked the settings in the volume
database and for all volumes the entry is similar to
following.<br>
<br>
controller_node:3260,3
iqn.2010-10.org.openstack:volume-00000004 <br>
<br>
But it seems these entries are being generated
automatically, i.e. as soon as I issue volume creation
command. How do I fix this? I am already using properly
configured iscsi_ip_address option in the controller's
nova.conf file.<br>

<div>It is set from the cofig iscsi_ip_address, so if
you have not set that configuration option to a
routable ip from compute -> volume then it will not
work. Also, changing the config option will not
change the existing values in the db, so you might
have to change those manually.</div>

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>

<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
moz-do-not-send="true"
href="http://paste.openstack.org/show/17470/"
target="_blank">

2) compute node (nova.conf - <a
moz-do-not-send="true"
href="http://paste.openstack.org/show/17469"
target="_blank">
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>
2012-05-14 17:32:13 TRACE
nova.rpc.amqp ProcessExecutionError:

command.<br>
