This is the liberty version of an RDO allinone install of Openstack.

I added a cinder volume and compute node on a second server and add it in using the the add a node instructions on RDO website. I can make volumes on the new iscsi LVM storage but cant connect it to instances.

Message
    Build of instance 7fb7ebc8-3f0c-46f7-b958-ecc51023386a aborted: Block Device Mapping is Invalid.
