Attila Doroszlai commented on HDDS-8447:
----------------------------------------
If datanode does not process delete container command for failed volume, will
it not be retried? Shouldn't it remove the container from in-memory state,
while leaving the container contents on the disk?

> Key: HDDS-8447
> URL: https://issues.apache.org/jira/browse/HDDS-8447
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Datanode
> Reporter: Arun Sarin
> Priority: Major
>
> Before HDDS-6449, if there was an error deleting containers from datanodes,
> the operation would be abandoned, leaving behind container pieces which could
> be problematic on restart. After that fix, deletion is more robust and moves
> the container to a volume specific tmp directory before deletion. This
> requires the volume to be present and healthy otherwise it will fail and the
> DN will be stuck in a container delete retry loop. In this jira, we will:
> 1. Check if the volume is in the failed volume set before deleting a
> container.
> 2. Trigger an on-demand volume scan if there is an IO error deleting the
> container.
