Doc Text:
In Red Hat OpenStack Platform (RHOSP) 17.0, the DNS service (designate) and the Load-balancing service (octavia) are misconfigured for high availability. The RHOSP Orchestration service (heat) templates for these services use the non-Pacemaker version of the Redis template. + Workaround: include `environments/ha-redis.yaml` in the `overcloud deploy` command after the `enable-designate.yaml` and `octavia.yaml` environment files.

Description Brent Eagles 2022-09-14 13:11:56 UTC 
This affects deployments where there is more than one redis instance, including the typical 3 controller default deployment. Deployments with tls-e are more severely affected as redis instances aren't configured in a way that allows them to replicate.

By default, environments/services/octavia.yaml, environments/services/designate.yaml and environments/enable-designate.yaml use the non-pacemaker version of the redis template. The non-pacemaker version likely hasn't been tested in HA environments and doesn't include configuration support for tls-e. 

Some possible options:
 - separate ha environemnt files for octavia and designate to include redis
 - make pacemaker a requirement for octavia and designate and have the default environment files include the pacemaker redis instead
 - create a non-pacemaker dependent version of the redis deployment
Comment 1 Brent Eagles 2022-09-14 13:16:16 UTC 
An immediate workaround is to make sure environments/ha-redis.yaml is included in the overcloud deploy command line after designate or octavia is specified on the command line.
