Our OpenStack has only one region and it's name is "nova".
When I tried to create cluster in CloudBreak WEB UI, Region in Configure Cluster TAB was "local" in the default.
I couldn't change it.
So I went on "create cluster process" as Region was "local".
Then, I clicked "create and start the cluster" button and got ERROR:
Instance creation failed: [ resourceType: OPENSTACK_INSTANCE, resourceName: cl09152-cbgateway-0-20160915014944 ] [ Cause message: Invalid volume: Instance 3310 and volume 9b7ffd05-d759-44e9-8f50-6996e8532763 are not in the same availability_zone. Instance is in None. Volume is in nova ] .
It seemed that this ERROR was caused by "local" region which I couldn't change.
I tried to create and start the cluster by CLI:Cloudbreak Shell, too.
But CLI:Cloudbreak Shell seemed not to support "stack create --OPENSTACK" and "cluster create" command.
