How to add a new node to cluster

From example above, suppose we want to add node with id 6 and host localhost:5006.

Start the server.

./server --id=6 --host=localhost --port=5006

On client, add the node as nonvoter

add_nonvoter 6 localhost:5006

After the log is replicated, set the node as voter

add_voter 6 localhost:5006

How to remove node from cluster

From example above, suppose we want to remove node with id 3 from cluster

Set the node as nonvoter

demote_voter 3

After the node is set as nonvoter, remote it from cluster

remove_server 3
