Rebuilding an instance can cause data loss if there are local disks so this is not something that should be done automatically. That\u0027s that reason that evacuate is an admin action and Nova has so far resisted any attempt to automate it.\n\nIf this automated rebuild were to happen from a user pov they would see their instance go down and then come back up shortly afterwards and they would be missing data. Requiring an admin to do it means someone makes a choice that losing data is better than trying to fix the hardware on the host.","commit_id":"93193b65a78e00302adbc3c0da2e4b0110749701"}]}
