Hi All,

I am attempting to install and configure OpenStack Mitaka on a 4 node stack. 1 Controller, 1 Compute, 1 Block Storage, and 1 Object Storage. When attempting to create the Block storage node I am unable to create a volume via the dashboard. The base OS os Ubuntu 14.04, and like I said earlier the Mitaka release of OpenStack.

Here is the cinder.conf on the Controller Node

[DEFAULT]
rootwrap_config = /etc/cinder/rootwrap.conf
api_paste_confg = /etc/cinder/api-paste.ini
iscsi_helper = tgtadm
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
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 10.0.0.11
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
iscsi_protocol = iscsi


[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = *********

[oslo_concurrency]
lock_path = /var/lib/cinder/tmp

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = **********


[database]
connection = mysql+pymysql://cinder:********@controller/cinder

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = tgtadm

Here is the cinder.conf on the Cinder (Block Storage) Node

[DEFAULT]
rootwrap_config = /etc/cinder/rootwrap.conf
api_paste_confg = /etc/cinder/api-paste.ini
iscsi_helper = tgtadm
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
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 10.0.0.41

[keystone_authtoken]
auth_uri = http://controller:5000

memcached_servers = controller:11211
auth_type = password

user_domain_name = default
project_name = service
username = cinder

enabled_backends = lvm
glance_api_servers = http://controller:9292

[oslo_messaging_rabbit]

#connection = mysql+pymysql://cinder:*******@controller/cinder
connection = mysql+pymysql://cinder:*******@controller/cinder
#connection = mysql://cinder:******@controller/cinder

[api_database]
connection = mysql+pymysql://cinder:*******@controller/cinder_api



[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = tgtadm

The status after I create the volume is "error". Here is the error line I get inside the cinder-scheduler.log file on there Controller Node

2016-09-07 17:14:22.291 10607 ERROR cinder.scheduler.flows.create_volume [req-272c5387-a2e3-4371-8a14-8330831910d0 a43909277cbb418fa12fab4d22e0586c 64d180e39e2345ac9bbcd0c389b0a7c4 - - -] Failed to run task cinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;volume:create: No valid host was found. No weighed hosts available

It's interesting, because before that error line there is a warning line above it saying:

2016-09-07 17:14:22.288 10607 WARNING cinder.scheduler.filter_scheduler [req-272c5387-a2e3-4371-8a14-8330831910d0 a43909277cbb418fa12fab4d22e0586c 64d180e39e2345ac9bbcd0c389b0a7c4 - - -] No weighed hosts found for volume with properties: {}

When I run the command "cinder service-list" from the Controller Node I get the following output:

+------------------+------------+------+---------+-------+----------------------------+-----------------+
|      Binary      |    Host    | Zone |  Status | State |         Updated_at         | Disabled Reason |

This leads me to believe that the Cinder Node and The Controller node are able to "see" or communicate with each other. I believe I have configured lvm properly inside the Cinder node. Just in case here is the filter section from the lvm.conf file:

 filter = [ "a/sda/", "a ...
