Comment 9 for bug 1872205

Ack, Kolla Ansible got this line in https://review.opendev.org/682095 (before there was just no coordination in Designate). I've done some further analysis in https://bugs.launchpad.net/kolla-ansible/+bug/1840070/comments/13

I will propose a proper fix on k-a side.

As for Designate, I guess two things need to be done: one is fixing logic for start/stop (it looks like it could fail due to something else and get in this weirdness), the other one is checking tooz features of selected backend to fail early with proper message (also message in docs for that it needs group membership in tooz).

As for tooz... I guess this is hardly a bug per se, I would switch it to wishlist so that maybe some day one implements this for etcd. Maybe. Considering other shortcomings of it, it needs a bit more work to be wide-scale production-ready.
