Final answer:
The series of statuses involved when running 'splunk offline --enforce-counts' on a peer node includes starting a graceful stop, decommissioning, peers adjusted, and offline complete, ensuring cluster integrity throughout the process.
Step-by-step explanation:
When running the splunk offline --enforce-counts command on a peer node in a Splunk cluster, it transitions through a series of statuses. This command is typically used to take a peer node offline while ensuring that the cluster's replication and search factor counts are not violated. When this command is issued, the peer node will go through the following statuses:
-
- Graceful stop initiated: When the enforce-counts command is first executed, Splunk Enterprise begins a safe-stop procedure.
-
- Decommissioning: The peer node begins decommissioning from the cluster's indexing activities, redistributing primary bucket copies if necessary.
-
- Peers adjusted: The cluster master node takes the necessary steps to adjust the presence of the offline peer in the cluster, preserving replication and search factors.
-
- Offline complete: Once all data has been safely replicated and the peer node has been removed from the cluster's activities, the process is complete and the node is successfully taken offline.
It's important to use the enforce-counts parameter when taking a peer node offline to ensure that data replication across the remaining active nodes maintains the integrity and availability of the data during planned outages.
