What happens if one of the nodes dies or needs to be replaced or removed
A: The config script has an option to remove a node from the cluster, but not for the primary node:
./config-sematext-apps.py remove --id <node_id>
The ID of the node can be found by running the status command:

What happens if the primary node dies or needs to be replaced
The cluster will not work without a primary node. To get the cluster up and running some manual steps will have to be executed. We plan to automate this in the very near future to to make things easy in these rare cases.
