Hi all,
If you're a nova operator, you probably know (and love) our increasing number of "heal $thing" commands in nova-manage. Despite appearances, we do not try to make these inconsistent, duplicative, and confusing. However, in reality, they pretty much are. Further, they require something being broken, an operator noticing, and then manual execution to (hopefully) fix things.
While reviewing another such proposed nova-manage command today, I decided to propose a potential solution to make this better in the future. I've got a spec proposed to create new standalone command/service for nova that will consolidate all of these into a very consistent interface, with a daemon mode that can be run in the background to constantly (and slowly) periodically audit these things and heal them when issues are found.
If you're an operator and have strong feelings on this topic, please review and opine here:
