Hi,

I have two Controllers/Service nodes running in Active/Active mode and a couple of HAProxy nodes to balance over them. I have Pacemaker running for L3 agent/metadata agent etc.

I'm using Galera as my cluster database, but the config guide in Openstack set the balancing method in HAProxy to 'service' - which will always select my Controller1 unless it goes down - then Controller2 will be used.

Would it not be more beneficial to set the balancing method to say; round robin and spread the load if multiple users are accessing horizon?

Do you think this way would be more likely to create problems with the Galera database?

thanks in advance.

Paul
