This can also be done with:

1. Start mnesia on new node with mnesia:start(). Thus creating a ram schema.

2. On the same new node do 

mnesia:change_config(extra_db_nodes, [any_existing_node@REDACTED]).

This should return {ok, [any_existing_node@REDACTED]} if successful.

3. Again on the new node do 

mnesia:change_table_copy_type(schema, node(), disc_copies).
