    And in the /var/log/syslog file, I have the error:
    Aug 20 15:01:00 WT-Openstack-22 kernel: [447693.534400] scsi29 : iSCSI Initiator over TCP/IP

    Aug 20 15:01:00 WT-Openstack-22 iscsid: conn 0 login rejected: initiator error - target not found (02/03)
    I have tried to fix this error for days but had no success.
    I built my cloud with the following instruction: http://docs.openstack.org/essex/open...l/apt/content/
    I built my cloud in an all in one node so the config for nova-volume is:
    volume_group=nova-volumes
    volume_name_template=volume-%08x
    iscsi_helper=tgtadm

    Re: [Openstack] Cannot attach volume to instances

    I think I just figured it:
    Because I followed different instruction, so I installed 2 packet: tgt and iscsitarget. Both of them are packets which used to manage the connections between the iSCSI storage subsystems in your storage area network. We must choose just one of them. It's will catch error if we install both.

    ps: I have read a lot of article about this problem: if you install the volume node in another host from compute node, you must have this options in nova.conf: iscsi_ip_address={volume IP}. If not, it catch this problem too

    Re: [Openstack] Cannot attach volume to instances

    I got hit with the same issue and i removed iscsitarget and rebooted the cloud box. its now attaching the volumes. Many thanks worked !!

    However, getting below logs in compute node
