Labels: pull-request-available (was: )
> Make Datanode disk space related commands and metrics clear
> -----------------------------------------------------------
>
> Key: HDDS-14446
> URL: https://issues.apache.org/jira/browse/HDDS-14446
> Project: Apache Ozone
> Issue Type: Improvement
> Components: DN, Ozone Recon, SCM
> Affects Versions: 2.1.0
> Reporter: Siddhant Sangwan
> Assignee: Siddhant Sangwan
> Priority: Major
> Labels: pull-request-available
>
> Ozone currently exposes Datanode disk space statistics (capacity, used space,
> available space) at various places - Datanode Web UI overview page, JMX
> volume info metrics, SCM JMX metrics, usageinfo command, Recon Datanodes
> page, Recon main overview page.
> However, the terms used to shows these stats are currently confusing. For
> example, if Recon is showing the Capacity of a Datanode with 1 volume as 500
> GB, that's actually the _capacity available to Ozone_. That is, raw disk
> capacity - du.reserved, not raw disk capacity.
> This jira aims to clarify these terms and make them consistent everywhere,
> except the main Recon overview page - that can be handled in a separate jira.
