Hi all,

I tried to configure Cinder as the glance backend store to store the image instead of storing them on the master node disk. However, I did not find an official introduction document. Is there anyone who can give me some hints? The openstack version is Mitaka on Ubuntu.

The following is the configure in glance_api.conf:

[glance_store]
stores = cinder,file,http
default_store = cinder
#filesystem_store_datadir = /var/lib/glance/images/
#cinder_api_insecure = False
#cinder_ca_certificates_file = None
#cinder_catalog_info = volumev2::http://svr-A7-A-U1:8776
#cinder_endpoint_template = http://svr-A7-A-U1:8776/v2/%(tenant)s
#cinder_http_retries = 3
#cinder_os_region_name = regionOne
#cinder_state_transition_timeout = 300
#cinder_store_auth_address = http://svr-A7-A-U1:5000
#cinder_store_password = qweasd
#cinder_store_project_name = service
#cinder_store_user_name = cinder

The error in the cinder node is as following:
