Hi folks, I want to discuss cluster reconfiguration scenarios, i am aware of 2 such bugs:
- ceph-mon not installed on controllers if cluster initially was deployed without ceph-osd - config with rabbitmq hosts not updated on non-controlles nodes after additional controllers is added to cluster [1] In both cases we need to track node state and change it accordingly to some event (additonal ceph-osd, additional controller added to cluster, etc..). I think that it is generic scenario and our api should support such modifications. To track state of node we need to introduce new state - something in lines of "requires_update". And extend deployment selection logic to include nodes with this state, if deploy action will be invoked. What do you think about such feature? I would be grateful for any other cases.
