Hi Vish,
Yeah you are right. I checked the settings in the volume database and
for all volumes the entry is similar to following.
controller_node:3260,3 iqn.2010-10.org.openstack:volume-00000004
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.
Regards,
Shashank Sahni

It should be getting the connection properties via the call to the
volume node. Is it possible your volume in the database has incorrect
properties stored in provider_location?
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.

Hi,
Thanks for the reply.
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.
I'm not using iscsitarget as per that document. Installation of
nova-volume on ubuntu precise automatically took care of it using tgt.
Kind Regards,

Hi,
I set this option in the configuration files of both compute and
controller. Restarted the service, but unfortunately same result.

Hi,
do you have the flag iscsi_ip_prefix configured in your nova.conf ?

Hi everyone,
I'm trying to configure a multi-node installation. Here is a brief
overview.
1) controller - api+network+scheduler+novnc+glance+keystone
(nova.conf - http://paste.openstack.org/show/17470/)
2) compute node (nova.conf - http://paste.openstack.org/show/17469)
3) volume node(single)
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.
2012-05-14 17:32:13 TRACE nova.rpc.amqp ProcessExecutionError:
Unexpected error while running command.
2012-05-14 17:32:13 TRACE nova.rpc.amqp Command: sudo nova-rootwrap
iscsiadm -m node -T iqn.2010-10.org.openstack:volume-00000003 -p
controller:3260 --rescan
2012-05-14 17:32:13 TRACE nova.rpc.amqp Exit code: 255
2012-05-14 17:32:13 TRACE nova.rpc.amqp Stdout: ''
2012-05-14 17:32:13 TRACE nova.rpc.amqp Stderr: 'iscsiadm: No portal
found.\n'
Any suggestions?
Kind Regards,
Shashank Sahni
