Hey folks, Does anyone have experience using zookeeper or redis to handle HA failover in cinder clusters?
I'm guessing you mean failover of an active/passive cinder-volume service?
I know there's docs on pacemaker, however we already have the other two installed and don't want to add yet another component to package and maintain in our clusters.
I'm afraid I don't, but if you make any progress on this, please let me know as it would be great to document: - how this would work - any pros and cons vs. Pacemaker and maybe I can help with that. One particular question: if the node running the service becomes unreachable, is it safe to fail it over straight away, or is fencing required first? (I'm pretty sure I've asked this same question before, but I can't remember the answer - sorry!) _______________________________________________ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
