Hi Vish,<br>
<br>
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>
<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>

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

running command.<br>
