Uninstall the Splunk Data Stream Processor

Once you uninstall the Splunk Data Stream Processor (DSP), you can perform a clean reinstallation. See Install the Data Stream Processor in this manual.

The following instructions assume that you have system administrator (root) permissions. If you do not have root permissions, you can use the sudo command to run the necessary scripts required to uninstall DSP.

Step 1: Remove (leave) all nodes from the cluster

To uninstall DSP, first remove all nodes from the cluster.

  1. From the working directory of a node, use the leave command. Repeat on each node.
  2. Once you only have one node left in your cluster, force the leave command to run.
    ./leave --force 

Once the last node leaves the cluster, the uninstall process kicks off. You'll see the following output once complete.

Depending on the state of your cluster, the uninstall process could take up to several hours to complete.

Step 2: Remove Gravity

After removing all nodes from the cluster, clean up the Gravity directory.

Run the following from the working directory:

rm -rf gravity/.gravity

After you've completed both steps, you can now perform a clean reinstallation of DSP.
