This patch drops the hacky workaround of using backend_host which is not recommended by the Cinder team and instead uses active-active RBD which has been implemented since Rocky. Closes-Bug: #1837403 Change-Id: I0c8aed4d0608c1f117e1baa1f428875956159ffd

features: | ||
- Cinder is deployed with Active-Active enabled by default if you are using | ||
Ceph as a backend storage. | ||
issues: | ||
- The previous way of using a common backend_host across all deployments | ||
was not recommended by the Cinder team and it will cause duplicate | ||
messages that cause problems in the environment. | ||
upgrade: | ||
- It is possible that you may need to use the cinder-manage command to migrate | ||
volumes to a specific host. In addition, you will have to remove the old | ||
``rbd:volumes`` service which will be stale. |
