If you still have the problem when running keystone with only 1 controller, then the cause is not related to the HA setup.

Jup, thats the one.

Could you stop httpd on all but one controller to see if the issue persists?

Did a quick search and active/active should have been working for ages. What is in your "catalog", "identity" and "token" sections?

I don't think keystone can run active/active in Juno. Look at my own question here (sadly no answers yet). Follow the HA Guide to set it up in active/backup mode or switch to Liberty or Mitaka.

Anyway, you could easily find out if caching is the cause by disabling it. Also it's worth noting that before a certain release (and I think it's liberty) active/active is not supported by keystone.

Ok, your galera cluster should be fine. Which version of openstack are you running since i'm not familiar with the memcached_servers directive.

You say memcached is running on both controller nodes. Do both controllers use both memcached servers? Did you specify memcached "host" or "hosts" option?

Are you sure your galera cluster is operating correctly? Which version of mysql-(galera)-server are you running and how did you start it?

You should be able to have both. There is only one restriction. The two agents can not be active on the same node at the same time. You need two separate network nodes, one for v1 and another for v2. Since DevStack runs everything on one single node, you can never have both there.

2016-04-07 03:40:22 -0600 answered a question Keystone authentication failure in a HA Setup

To have keystone in an active/active setup they must:

  1. Be connected to a clustered (or replicating) database
  2. Be using the same pool of memcache servers

Before anyone can help you further, you should tell more about your setup. Are the above 2 requirements met?

2016-03-30 10:50:07 -0600 asked a question Which services can not run active/active in Liberty

At this time the HA guide is still a work in progress and seems to be outdated in some sections (at least in respect to newer openstack releases)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