Fixed In Version: heketi-9.0.0-12
Doc Type: Enhancement
Doc Text:
With this update, Heketi’s device remove operation is fully tracked and based on a series of brick eviction operations , thereby making the overall process much more reliable. Heketi used to track an operation for overall device replacement but that operation did not track the underlying changes Heketi was making to volumes as part of a device remove operation. When an error was encountered during the device remove operation, the lack of detailed tracking could have lead to database inconsistency with Gluster, creating a need to manually repair the database.

Description John Mulligan 2020-03-10 14:56:06 UTC 
Description of problem:

The last large action customers take using heketi that is not based on reliable operations metadata is 'device remove' / 'device replace'. Changing this to be based on operations would greatly improve the reliability of the system and allow the heketi auto-clean behavior to assist with keeping the db in a good state.


In theory this would reduce the number of times support team would need assistance from developers and avoid having to edit the db as json.
