[openstack-dev] [nova] compute - conductor and version compatibility

2015-08-17 Thread Markus Zoeller
I have the impression that more and more people try to run OpenStack in a mixed-releases-mode and face some troubles to understand how the capabilities and limitations look like. For example, the reporter of [1] runs a nova-conductor (Juno) with a nova-compute (Kilo). I tried in comment #3 of [1]

No, that's not valid behaviour. You need to upgrade the controller infrastructure (conductor, API nodes, etc) before any compute nodes. Yep. --Dan signature.asc Description: OpenPGP digital signature __ OpenStack
