> Key: HDDS-13328
> URL: https://issues.apache.org/jira/browse/HDDS-13328
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: Ozone Manager
> Reporter: Soumitra Sulav
> Assignee: Soumitra Sulav
> Priority: Major
>
> Add a Case for Byteman fault causing BCSID mismatch, and finally, Force Delete.
> {code:java}
> Modify Configuration for Faster State Transitions
> Apply the following configurations to accelerate container state transitions and enforce pipeline limits on the cluster:
> hdds.scm.replication.thread.interval: 5s
> ozone.scm.datanode.pipeline.limit: 1
> hdds.scm.wait.time.after.safemode.exit: 5s
> Apply the byteman rule to block putblock to introduce inconsistent container state and notifyGroup remove to disable QuasiClosed container state.
> Do this on Datanode 1 and have only 3 running datanodes in the cluster
> Initiate a New Pipeline and Container
> Close all active pipelines to ensure that the next write operation triggers a new pipeline and container creation.
> Monitor Container State Across All Datanodes
> Identify and observe the container state on all three datanodes.
> Stop Datanode 1 & Transition the Container to a Closed State
> Shut down Datanode 1 and close the associated pipeline.
> Monitor the container state— it should move to the CLOSING state and eventually transition to CLOSED.
> Verify the transition by fetching the dn-container.log.
> Restart Datanode 1 & Validate Container State
> Bring Datanode 1 back online and check its reported container states.
> Wait for the container to transition— it should move to CLOSED but with a 0 BCSID.
> Bring Down the Remaining Datanodes & Restart SCM
> Shut down any two datanodes from the remaining set.
> Select two random datanodes to allow SCM to restart without entering safe mode.
> Restart SCM and Datanode 1, ensuring that the container is marked EMPTY sooner due to a fresh volume container reload.
> Confirm Container Deletion
> Since the container has a 0 BCSID, Datanode 1's container should be marked EMPTY and queued for deletion.
> Verify the container state using admin container info.
> Restart Remaining Datanodes & Validate Deletion Propagation
> Bring the other two datanodes back online.
> Confirm whether the container deletion is propagated to these nodes.
> If the container had a non-zero BCSID in an unstable cluster, a Force Delete may be triggered, ensuring its removal from all datanodes.
