Whiteboard
There are two types of actions as foundation of health management functions: check and recover.
There are three ways to trigger these actions:
(1) manual: expose the two actions as REST API so that users can manually request these
actions.
(2) semi-auto: add listener to nova in health_manager. Once some nodes are dead, the
check actions are triggered to see if any inconsistency with status stored in
Senlin DB -- the check actions will update the DB automatically.
(3) automatic: in addition to auto-triggering of the check actions, we will trigger
the recover actions periodically to recover nodes in ERROR status.
If automation is expected in (2) and (3) above, an admin should define a health
policy for their clusters which need special health management (auto-check and
auto-recover). If no policy is found attached, manual triggering of actions will be
the only choice.
Based on discussion with all core members, we will target to support manual and semi-auto cases in Mitaka-3. Will enable implements to automatic scenario once discussion with product line and customers settled down.
