Mnesia :bad_type error

[danschultzer]

Distillery doesn't include the :mnesia app by default, so you'll have to explicitly state that it's an included application in your mix.exs for it to be built into your release:

defmodule MyApp.Application do
  use Mix.Project

  # ...

  def application do
    [
      mod: {MyApp.Application, []},
      extra_applications: [:logger, :runtime_tools],
      included_applications: [:mnesia] # <--- Add to :included_applications
    ]
  end

  # ...
end

I'm not sure if it'll be picked up in :extra_applications.

Also, if you experienced a failed start of your app the first time you deployed, because mnesia wasn't available, then remove the initialized mnesia data files in production and restart with the fixed version. I've experienced that these initialized files can't be used if the whole app is halted.

FWIW, I had trouble get this running myself the first time around. This was a production app with a few hundred daily visitors. The mnesia errors are difficult to read, but ever since I got the mnesia files initialized properly it has been working 100% of the time.

@jung-hunsoo did you get this working?

[jung-hunsoo]

@danschultzer Oh sorry. I've been in other issues..

Yeap, it's working now. Both dev and prod works fine. Actually I don't know it's working properly. At least it showed no error.

Great! It's working with mnesia if there's no errors.
