Andrey Yarovoy commented on HDDS-14800:
---------------------------------------
DB handle needs to implement closeable interface and close DB only if there are
no other handles used by concurrent threads.
> Check DB open state during one container scanning in
> BackgroundContainerDataScanner

> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Sammi Chen
> Assignee: Priyesh K
> Priority: Major
>
> StorageVolumeChecker and BackgroundContainerDataScanner are running in
> parallel.
> When StorageVolumeChecker detects a volume check fails twice(configurable),
> it will fail the volume, close the rocksdb for this volume.
> Since BackgroundContainerDataScanner doesn't get notified for DB close, so it
> should check the DB open/close state during a container's scan, before
> calling rocksdb APIs.
