Re: [Openstack] Problem with attaching disks to an instance

[Shashank Sahni]

Hi, 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. controller node - http://paste.openstack.org/show/17513/ compute node - http://paste.openstack.org/show/17514/ volume node - http://paste.openstack.org/show/17515/ As per my understanding, I just need to figure out how the volume node is identified. Thank you for replying.

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.

Restarted the service, but unfortunately same result. Regards, Shashank Sahni On 05/14/2012 05:58 PM, Razique Mahroua wrote: Hi, do you have the flag iscsi_ip_prefix configured in your nova.conf ? Razique Shashank Sahni 14 mai 2012 14:22 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?
