Final answer:
When running Splunk offline on a peer node, the statuses will progress from 'Shutting down' to 'Offline.' After resolving any issues and bringing the node back, the status proceeds to 'Recovering,' and finally, back to 'Up' once it is in sync with the indexing cluster.
Step-by-step explanation:
When running Splunk offline on a peer node, there is a specific series of statuses that indicate the state of the node. First, the node will display "Shutting down" as it begins the process. Subsequently, it will show "Offline" once it has fully disconnected from the indexing cluster. During the offline period, the peer will not index data or participate in cluster replication. After maintenance or the issue causing the offline state is resolved, the admin can bring the node back online, and its status will change to "Recovering", where it will catch up on indexing and replicate missing data. Once it's fully recovered and in sync with the cluster, its status will return to 'Up'.
