--------------------------------
Summary: SCM Pending Deletion should report replicated block size
instead of block size
Key: HDDS-14625
URL: https://issues.apache.org/jira/browse/HDDS-14625
Project: Apache Ozone
Issue Type: Sub-task
Components: Ozone Recon
Reporter: Priyesh K
Assignee: Priyesh K
In the Cluster Capacity UI, the *Pending Deletion* card is currently displaying
the _unreplicated_ size. However, this does not accurately reflect the actual
space being held by SCM tasks.
The intention is to show the *total space occupied across the cluster* by
blocks that are pending deletion. Since data is replicated, the space impact is
based on the {*}replicated size{*}, not the original key size.
For example, if a 100 MB key is deleted and the replication factor is 3, SCM is
actually holding *300 MB* (100 MB × 3) worth of block data across the datanodes
until deletion is completed. Therefore, the UI should display the {*}total
replicated pending block size{*}, as this represents the real storage consumed
in the cluster.
