Mnesia doesn't quite work by having a primary-secondary architecture. Instead, some nodes have local copies of data, and some have remote copies. (You can see this by running mnesia:info() from the console. There is a list of remote tables, and a list for each of the local-tables: ram_copies,disc_copies and disc_only_copies.)
Mnesia is a Database Management System (DBMS) that ships with the Erlang Runtime System which we can use naturally with Elixir. The Mnesia relational and object hybrid data model is what makes it suitable for developing distributed applications of any scale.

Data in Mnesia is organized as a set of tables. Each table has a name that must be an atom. Each table is made up of Erlang records. The user is responsible for the record definitions. Each table also has a set of properties. The following are some of the properties that are associated with each table: type.

If Mnesia malfunctions, system information is dumped to file MnesiaCore.Node.When. The type of system information contained in this file can also be generated with the function mnesia_lib:coredump(). If a Mnesia system behaves strangely, it is recommended that a Mnesia core dump file is included in the bug report.
Mnesia is the somewhat odd name for the real-time, distributed database which comes with Erlang. 11.1 What is Mnesia good at?

When to use a particular piece of technology is often a confusing pursuit. mnesia:delete_schema/1 fails if any of the Erlang nodes given as DiscNodes is not alive, or if Mnesia is running on any of the nodes. After the database has been deleted, it may still be possible to start Mnesia as a disc-less node. Mnesia doesn't quite work by having a primary-secondary architecture.

Mnesia is a distributed, soft real-time database management system written in the Erlang programming language. It is distributed as part of the Open Telecom Platform.
Each table is made up of Erlang records. The user is responsible for the record definitions. Each table also has a set of properties. The following are some of the properties that are associated with each table: type.
