Description Gregory Charot 2023-03-17 18:17:55 UTC

Description of problem:

In 17.1 we are productizing cinder backup active / active, this will be the default supported way of deploying cinder backup.
RFE: https://bugzilla.redhat.com/show_bug.cgi?id=1666804

Up to 16.1 / 17.0 we are deploying cinder backup as active / passive under pacemaker, this will still be supported in OSP17.1 for upgraded clusters but we are announcing the deprecation of Active / Passive as it will be removed in a future release (OSP18).

Upgraded cluster can keep active / passive during the 17.1 cycle or migrate to active active, a procedure will be published after 17.1 GA 
https://bugzilla.redhat.com/show_bug.cgi?id=2128012

On the doc side we need to announce the active / passive deprecation in the release notes under the "deprecated functionality" section. 
Example with OSP17.0 https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/17.0/html-single/release_notes/index#deprecated_functionality

The 17.1 cinder backup product documentation should also state that active/passive is deprecated.
