At this time the HA guide is still a work in progress and seems to be outdated in some sections (at least in respect to newer openstack releases)

It's not clear to me which services can definitely not run in an active/active setup in Liberty. The HA guide seems to imply I can not have multiple services running for:

  • keystone:

    to me it seems this only applied to Juno and before.

  • glance:

    is this true when the used backend is HA, like Ceph?

  • cinder:

    seems not to apply when the used backends are HA, like Ceph.

I would sure like a definitive answer on this.
