Kindly let me know the prerequisite for configuring the cinder node in separate server.

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 ;)

Thanks alot Khanh Nguyen for your help throughout the debugging.

Issues was very simple, i dint have the timesync in both the nodes!!!!

That's why it could not find the second server services.

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