To remove a node from a cluster, stop the Spectrum Technology Platform server.
-
To stop the server, right-click the Spectrum Technology Platform icon in the Windows system tray (shown below) and select Stop Spectrum.
-
Stop the node you want to remove:
On Windows, right-click the Spectrum Technology Platform icon in the system tray and select Stop Spectrum.
-
Open the file server/conf/spectrum-container.properties in
a text editor and set spectrum.cluster.enabled to
false.
-
On each of the other nodes in the cluster, open the
spectrum-container.properties file and remove the node from
the spectrum.cluster.seeds property.
For Spatial users: If you want to keep the node
standalone and able to run outside the cluster, copy back the original
repository.xml file and remove the following folders from the
/server/modules/spatial/jackrabbit directory for each instance
of Spectrum Technology Platform: repository, version, workspaces. Restart the
server and import the repository content.
