Hallo all,

I am trying to attach a volume to an instance using cinder in Havana and get an error which is pasted below. The following services are running on the controller node: cinder-api, cinder-scheduler, cinder-volume, tgt and services related to nova. In the compute node, the iscsi daemon is running apart from compute and networking services. In the compute node when I perform discovery, I am able to get a response from the ISCSI target.

I have the following flags set in cinder, nova.conf of the controller and compute node

a)      iscsi_ip_address=<iscsi ip address>

b)      volume_group=cinder-volumes1

c)       volume_name_template=volume-%s

d)      volume_api_class=nova.volume.cinder.API

e)      iscsi_helper=tgtadm

Can I kindly seek help from the forum to resolve this problem?

Best regards,
