-----------------------------------
Resolution: Duplicate
> [snapshot] Referenced and exclusive size not populated properly when snapshot
> is created after Trash deletion
> -------------------------------------------------------------------------------------------------------------
>
> Key: HDDS-9431
> URL: https://issues.apache.org/jira/browse/HDDS-9431
> Project: Apache Ozone
> Issue Type: Bug
> Components: Snapshot
> Reporter: Jyotirmoy Sinha
> Assignee: Aswin Shakil
> Priority: Major
> Labels: ozone-snapshot
>
> Steps :
> # Create vol/buck/key
> # Create snapshot snap1
> # Delete key - moved inside .Trash
> # Create snapshot snap2
> # Delete .Trash of above bucket
> # Create snapshot snap3
> # Delete snapshot snap2
> # Check referenced and exclusive size of snapshots
> Expected behaviour - Referenced size of snapshot snap3 should be 0, since it
> holds no keys. Exclusive size of snap1 should be equal to key size since its
> the only snapshot that holds the key.
> Observed behaviour - Referenced size of snapshot snap3 == snap1. Exclusive
> size of snapshot snap1 = 0
> Snapshot file contents -
> {code:java}
