We've had luck mismatching major versions as outlined above. Specifically, running Juno (2014.2.x) versions of heat/ceilometer with Icehouse (2014.1.x) versions of everything else. But, also to Kris's point, I'd probably be careful to keep nova/neutron in pretty close lockstep as there's a lot of dependencies between the two. I should also point out, doing the above creates some logistical issues. Specifically: ceilometer-compute-agent needs to be juno version, but it runs on the compute nodes so you need to be careful about dependencies between it and nova-compute, the ovs-agent and whatever other things you've got running on the node. This was something we discussed a little bit at the operators meet-up in Philly (venvs, VMs, containers, etc.), but it's worth pointing out that in some cases it's possible you'll run into similar situations with minor versions' requirements as well. -- Kevin > ____________________________________________ > > Kris Lindgren > Senior Linux Systems Engineer > GoDaddy, LLC. > > > From: Daniel Comnea <[email protected]> > Date: Monday, March 30, 2015 at 1:19 PM > To: Daniel Comnea <[email protected]> > Cc: "[email protected]" > <[email protected]>, "OpenStack Development Mailing > List (not for usage questions)" <[email protected]> > Subject: Re: [Openstack-operators] [Openstack-dev][all] how to apply > security/back-ported release to Icehouse production > > No thoughts? > > > > On Sat, Mar 28, 2015 at 10:35 PM, Daniel Comnea <[email protected]> wrote: > Hi all, > > Can anyone shed some light as to how you upgrade/ applies the > security/back-ported patches? > > E.g - let's say i already have a production environment running Icehouse > 2014.1 as per the link [1] and i'd like to upgrade it to latest Icehouse > release 2014.1.4. > > Also do you have to go via sequential process like > > 2014.1 -> 2014.1.1 -> 2014.1.2 -> 2014.1.3 -> 2014.4 or i can jump from > 2014.1 to 2014.1.4? > > And the last questions is: can i cherry pick which bugs part of a project to > pull?
