Hello, sorry I could not make it to the PTG.
I have an idea that I want to share with the community. I hope this is a good place to start the discussion. After years of Openstack operations, upgrading releases from Icehouse to Newton, the feeling is that the control plane upgrade is doable. But it is also a lot of pain to upgrade all the compute nodes. This really causes downtime to the VMs that are running. I can't always make live migrations, sometimes the VMs are just too big or too busy. It would be nice to guarantee the ability to run an updated control plane with compute nodes up to N-3 Release. This way even if we have to upgrade the control plane every 6 months, we can keep a longer lifetime for compute nodes. Basically we can never upgrade them until we decommission the hardware. If there are new features that require updated compute nodes, we can always organize our datacenter in availability zones, not scheduling new VMs to those compute nodes. To my understanding this means having compatibility at least for the nova-compute agent and the neutron-agents running on the compute node. Is it a very bad idea ? Do other people feel like me that upgrading all the compute nodes is also a big part of the burden regarding the upgrade ? thanks !
