Dear all, Hi I'm building two OpenStack - Juno System.

I'd like to share one CinderNode with two OpenStack System. The CinderNode is created two volume group (cinder-volume1 and cinder-volume2).

Openstack1 --> use cinder-volume1 Openstack2 --> use cinder-volume2

Do you have any ideas?

You could look into having multiple versions of Cinder running. You could just install NFS on the node you want to share. If you install NFS then you can setup different exports. For each configuration of Cinder on the controllers you can use a different export.

Cinder for Juno 1 would have the export:


While the second could use:


You'll definitely want to look into NFS - setup the volume groups then setup the exports to use the space in the volume groups. Then use the Cinder + NFS guides to access the exports and configure NFS as a back-end for Cinder.

If you can figure out how to get the Cinder processes to run in multiples without issues then you could setup keystone endpoints on the different OpenStack setups to point to the Cinder API endpoint on the CInder node. Keystone just cares about where the APIs are. Keep in mind you'll need to use this same IP for any configuration files where you have to configure Cinder API access.
