Ethan Rose commented on HDDS-8824:
----------------------------------

[~sumitagrawl] [~deveshsingh] continuing our discussion on quota repair options beyond those provided in the HDDS-8742 [PR|https://github.com/apache/ozone/pull/4817]. Recon could be an option but we do not currently have a framework for doing repair operations from Recon in a consistent manner. Developing that would a be pre-requisite to any Recon repair task. The {{ozone repair}} CLI outlined in HDDS-8100 will be much simpler to implement as a requirement for this tool. The tool also only has niche use cases, so it may not warrant space on Recon's UI.

> quota count can go wrong based on bug in the system. All the known bug is fixed with parent task HDDS-7479 related to quota calculation whenever file/keys/directories are added/removed.
> And upgrade is provided with HDDS-8742.
> CLI based tool provide offline capability for recalculating quota,
>  * For keys/files with 1 billion takes approx 30 minutes, so this can be run in offline mode
>  * can be triggered at bucket level
>  
> Few impact to be takenup:
>  * snapshot impact needs to be handled as quota is shared between snapshot db and active db.
