devstack multinode fails during cinder volume type creation

[Sasikanth Eda]

Hi, I am trying to create a multi-node setup using process described in http://docs.openstack.org/developer/devstack/guides/multinode-lab.html

On the compute node, stack.sh fails to create lvm type.

Please provide configuration from controller node.

Hi this is the configuration setting used for controller node;

Confirmed.

Devstack crashed if Cinder will be installed to compute node.

Controller node:
+ cinder type-create lvmdriver-1
+--------------------------------------+-------------+
| ID | Name |
+--------------------------------------+-------------+
| 4efa7b39-aa16-48fa-80cf-fbaacbbb1b62 | lvmdriver-1 |
+--------------------------------------+-------------+
+ cinder type-key lvmdriver-1 set volume_backend_name=lvmdriver-1

Compute node:
+ cinder type-create lvmdriver-1

++ local r=1
++ set +o xtrace
stack.sh failed

[Andrey Alekov (aalekov)]

Not bug. Configuration problem.

Add option CINDER_SERVICE_HOST=controller_node_ip to compute node.
Remove services "c-sch,c-api" from compute node.

thanks Andrey, worked now.
