    Let's say we need to join two node nodeA & nodeB. Then makesure both the node has the same erlang-cookies & basics ports are open
    i.e needed to communicate nodes internally.

    Steps:
    1. Ensure all the node has the same erlang-cookies.
    2. Now go to any one of the node let's say we wish to add NodeB to NodeA cluster. Then go to the NodeB & run the following command.

    Node = NodeAName.
    net_adm:ping(Node). #==> Check if node can connect with each other. If the response is Pang abort & fix the issue first & then comeback.

    application:stop(ejabberd).
    application:stop(mnesia).
    mnesia:delete_schema([node()]). # Delete old schema
    application:start(mnesia).
    mnesia:change_config(extra_db_nodes, [Node]).
    mnesia:change_table_copy_type(schema, node(), disc_copies).

    spawn(fun() ->
    lists:foreach(fun(Table) ->
    Type = call(Node, mnesia, table_info, [Table, storage_type]),
    mnesia:add_table_copy(Table, node(), Type)
    end, mnesia:system_info(tables)--[schema])
    end).
    application:start(ejabberd).


    After running all the above command successfully. You can check if the node has been added to the cluster or not by running
    mnesia:info() command. This should list all the clustered node under "running db nodes" key.
