for me, I installed all on the storage node.

you should innstall openstack packages and ntp for your node

for the simple deployement, i suggest you install one cinder-api, and cinder-scheduler on controller node and install cinder-volume on the cluster nodes..

I included HA for these cinder services, so i installed all.

another options you to expand the storage nodes:

1. use multi-backend lvm volumes, see more detail in the guide: http://docs.openstack.org/trunk/openstack-block-storage/admin/content/multi_backend.html (http://docs.openstack.org/trunk/opens...)

2. select one the stable storage back-end, -> it's easier to extend more storage node dynamically. In my deployment, i'm using ceph likes as the storage back-end. ^.^

Hope they're useful to you ;)

Hi shausy, I encountered the same problem to yours. I don't know about the formula too, kindly let me know your resolution?

just do reproduce this case by creating new volume and attach the full log file for more detail in this issue.

Go ahead to install cinder component in another node. ^.^. Just remind, update correct end-point of cinder volume in keystore to new server path.
