Hi Joe,
Thanks for your reply, yes Me and Marco are working together.
I have tried to used
os_region_name = RegionOne
both in cinder.conf and nova.conf but no luck so far. But the error message is a bit different. It seems like now the system is recognising the region.
2015-12-10 09:32:54.661 26792 TRACE nova.api.openstack EndpointNotFound: internalURL endpoint for volume service named cinder in regionOne region not found
Following are my endpoints:

Again if I remove hpc2n everything started to work fine. Can you tell me what service I suppose to restart (if required)?

Hi Salman,
Someone mentioned this same issue yesterday in relation to Terraform (maybe a colleague of yours?), so given the two occurrences, I thought I'd look into this.
I have a Liberty environment readily available, so I created a second set of volume and volumev2 endpoints for a fictional region. Everything worked as expected, so I started reviewing the config files and saw that /etc/cinder/cinder.conf had an option
[DEFAULT]
os_region_name = RegionOne
I commented that out, but things still worked.
Then in /etc/nova/nova.conf, I saw:
[cinder]
os_region_name = RegionOne
commenting this out caused volume attachments to hang indefinitely because nova was trying to contact cinder at RegionTwo (I'm assuming this is the first catalog entry that was returned).
Given this is a Liberty environment, it's not accurately reproducing your problem, but could you check and see if you have that option set in nova.conf?
I have a Kilo environment in the process of building. Once it has finished, I'll see if I can reproduce your error there.
Thanks,
Joe

Hi,
I am using Kilo release on CentOS. We have recently enabled multiple regions and it seems that Cinder have some problems with multiple endpoints.
Thinks are working fine with nova but cinder is behaving strange. Here are my endpoints
