Try this.

One node1 or node2
================
mnesia:add_table_copy(schema, node3@REDACTED, ram_copies).

One node3@REDACTED
================
erl -sname node3@REDACTED -setcookie cookie

mnesia:start().

mnesia:change_config(extra_db_nodes, [node1@REDACTED]).

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

mnesia:add_table_copy(tt, node3@REDACTED, disc_copies).
