OpenStack summit Tokyo anyone? I've been there and thought it was a very well organized event, in a nice location. Every minute together with peers seemed worth it to me. This said, let's talk about the actual sessions. I spent most of my time at the TripleO and Heat sessions, with a little detour on Magnum. Plus some booth crawling.
We had three sessions and a full day meetup. The first discussed the recent …
Yes, EnablePacemaker! A little old fashioned and not very well suited for OpenStack you say heh? Let's try to talk a bit about this then. News is that we're adding into TripleO/Puppet an option to deploy Pacemaker on the Overcloud nodes. Puppet you said? Sure TripleO can use Puppet now for the configuration of the Overcloud nodes, ask Dan Prince :) Actually usage of Puppet is nowdays the preferred approach and many features are available …

First, a link to the cinder-ha blueprint, where you can find even more links, to the actual spec (under review) and the code changes (again, still under review). Intent of the blueprint is for the TripleO deployments to keep Cinder volumes available and Cinder operational in case of failures of any node.
This said, should $subject sound interesting to you, beware the code still …
One of the topics discussed during the TripleO mid-cycle meetup in RDU was our status in relation to deploying OpenStack in a highly available manner. This had been worked on for some time and recently reached a usable state.
Majority of complications seem to come from two factors: 1) we need to guarantee availability of external services too, like the database and the message broker, which aren't exactly designed for a scale-out scenario, 2) despite …
On OpenStack again. Glance is the component in charge of hosting the images (and image snapshots) to be cloned for the ephemeral instances. Images usually are just some random big files so it makes perfect sense to use Swift for such an object (a File Object storage)!
As usual, some assumptions before we start:
