Dear All, I installed iSCSI target at my controller node (IP: 192.168.106.20), #>iscsitarget open-iscsi iscsitarget-dkms
then modify my cinder.conf at controller node as below, [DEFAULT] rootwrap_config = /etc/cinder/rootwrap.conf api_paste_confg = /etc/cinder/api-paste.ini #iscsi_helper = tgtadm iscsi_helper = ietadm volume_name_template = volume-%s volume_group = cinder-volumes verbose = True auth_strategy = keystone #state_path = /var/lib/cinder #lock_path = /var/lock/cinder #volumes_dir = /var/lib/cinder/volumes iscsi_ip_address=192.168.106.20 rpc_backend = cinder.openstack.common.rpc.impl_kombu rabbit_host = controller rabbit_port = 5672 rabbit_userid = guest rabbit_password = demo glance_host = controller enabled_backends=lvmdriver-1,lvmdriver-2 [lvmdriver-1] volume_group=cinder-volumes-1 volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver volume_backend_name=LVM_iSCSI [lvmdriver-2] volume_group=cinder-volumes-2 volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver volume_backend_name=LVM_iSCSI_b [database] connection = mysql://cinder:demo@controller/cinder [keystone_authtoken] auth_uri = http://controller:5000 auth_host = controller auth_port = 35357 auth_protocol = http admin_tenant_name = service admin_user = cinder admin_password = demo Now I use the following command to create a cinder volume, and it can be created successfully. #> cinder create --volume-type lvm_controller --display-name vol 1 Unfortunately it seems not attach to a iSCSI LUN automatically because I can not discover it from iSCSI initiator, #> iscsiadm -m discovery -t st -p 192.168.106.20 Do I miss something?

The default value for iscsi_helper in cinder.conf is "tgtadm", I will change to "ietadm" to integrate with iSCSI target. Unfortunately I am not sure that iscsitarget should be installed at controller node or compute node? Have any reference? Regards, Johnson
