we have to be careful here, adding an extra job for this is probably the safest option but tripleo CI resources are a constraint, for that reason I would add it to the HA job (which is currently non voting) and once its stable we should make it voting. > > I'd be supportive of making it the default HA job in the longer term as > long as the LVM code is still getting tested somewhere - LVM is still > the reference implementation in cinder and after discussion there was > strong resistance to changing that. We are and would continue to use lvm for our non ha jobs, If I understand it correctly the tripleo lvm support isn't HA so continuing to test it on our HA job doesn't achieve much. > > I've no strong opinions on the node layout, I'll leave that to more > knowledgable people to discuss. > > Is the ceph/tripleO code in a working state yet?
