Openstack Cinder Proxy
Cinder-Proxy acts as the same role of Cinder-Volume in cascading OpenStack. Cinder-Proxy treats cascaded Cinder as its cinder volume, convert the internal request message from the message bus to restful API calling to cascaded Cinder.
Key modules
-
The new cinder proxy module cinder_proxy,which treats cascaded Cinder as its cinder volume, convert the internal request message from the message bus to restful API calling to cascaded Cinder:
cinder/volume/cinder_proxy.py
Requirements
- openstack-cinder-volume-2014.1-14.1 has been installed
Installation
We provide two ways to install the cinder proxy code. In this section, we will guide you through installing the cinder proxy with the minimum configuration.
-
Note:
- Make sure you have an existing installation of Openstack Icehouse.
- We recommend that you Do backup at least the following files before installation, because they are to be overwritten or modified: $CINDER_CONFIG_PARENT_DIR/cinder.conf (replace the $... with actual directory names.)
-
Manual Installation
-
Make sure you have performed backups properly.
-
Navigate to the local repository and copy the contents in 'cinder' sub-directory to the corresponding places in existing cinder, e.g.
cp -r $LOCAL_REPOSITORY_DIR/cinder $CINDER_PARENT_DIR
(replace the $... with actual directory name.) -
Update the cinder configuration file (e.g. /etc/cinder/cinder.conf) with the minimum option below. If the option already exists, modify its value, otherwise add it to the config file. Check the "Configurations" section below for a full configuration guide.
[DEFAULT] ... ###configuration for Cinder cascading ### volume_manager=cinder.volume.cinder_proxy.CinderProxy volume_sync_interval=5 cinder_tenant_name=$CASCADED_ADMIN_TENANT cinder_username=$CASCADED_ADMIN_NAME cinder_password=$CASCADED_ADMIN_PASSWORD keystone_auth_url=http://$GLOBAL_KEYSTONE_IP:5000/v2.0/ cascading_glance_url=$CASCADING_GLANCE cascaded_glance_url=http://$CASCADED_GLANCE cascaded_available_zone=$CASCADED_AVAILABLE_ZONE cascaded_region_name=$CASCADED_REGION_NAME
-
Restart the cinder proxy.
service openstack-cinder-volume restart
-
Done. The cinder proxy should be working with a demo configuration.
-
-
Automatic Installation
-
Make sure you have performed backups properly.
-
Navigate to the installation directory and run installation script.
cd $LOCAL_REPOSITORY_DIR/installation sudo bash ./install.sh
(replace the $... with actual directory name.)
-
Done. The installation code should setup the cinder proxy with the minimum configuration below. Check the "Configurations" section for a full configuration guide.
[DEFAULT] ... ###cascade info ### ... ###configuration for Cinder cascading ### volume_manager=cinder.volume.cinder_proxy.CinderProxy volume_sync_interval=5 cinder_tenant_name=$CASCADED_ADMIN_TENANT cinder_username=$CASCADED_ADMIN_NAME cinder_password=$CASCADED_ADMIN_PASSWORD keystone_auth_url=http://$GLOBAL_KEYSTONE_IP:5000/v2.0/ cascading_glance_url=$CASCADING_GLANCE cascaded_glance_url=http://$CASCADED_GLANCE cascaded_available_zone=$CASCADED_AVAILABLE_ZONE cascaded_region_name=$CASCADED_REGION_NAME
-
-
Troubleshooting
In case the automatic installation process is not complete, please check the followings:
-
Make sure your OpenStack version is Icehouse.
-
Check the variables in the beginning of the install.sh scripts. Your installation directories may be different from the default values we provide.
-
The installation code will automatically add the related codes to $CINDER_PARENT_DIR/cinder and modify the related configuration.
-
In case the automatic installation does not work, try to install manually.
-
Configurations
- This is a (default) configuration sample for the cinder proxy. Please add/modify these options in /etc/cinder/cinder.conf.
- Note:
- Please carefully make sure that options in the configuration file are not duplicated. If an option name already exists, modify its value instead of adding a new one of the same name.
- Please refer to the 'Configuration Details' section below for proper configuration and usage of costs and constraints.

#configuration item. but it is up to the admin to make sure the storage_availability_zone in cinder-proxy#and casacdede cinder keep the same value.
