How to reconnect a crashed erlang mnesia node to cluster again?

I'm learning erlang and mnesia. I have a question: how to reconncet a "crashed" erlang mnesia node to cluster again?

Erlang/OTP 17 [erts-6.2]

What I did:

Two mnesia nodes: m11@deb83-11 and m12@deb83-12. They were connected with each other well.
```
(m11@deb83-11)4> mnesia:system_info(running_db_nodes).
['m12@deb83-12','m11@deb83-11']
```
Then I teminated the erl shell of m12@deb83-12 by "Ctl-G" and "q" without stopping mnesia.
After that, I restarted erl shell for m12@deb83-12 node with same command line.

I found the restarted node m12@deb83-12 did not connect to m11@deb83-11.

(m11@deb83-11)16> mnesia:system_info(running_db_nodes).
['m11@deb83-11']

Note 1. If i stopped mnesia in step#2, m12@deb83-12 would reconnect to m11@deb83-11 successfully after step#3)

Note 2. I did not create any table. There is only an empty schema in this cluster.

Thanks in advance!

Solution

Apparently all you need to do is connect to the other node (so that nodes(). returns the other node) and restart mnesia with mnesia:stop(). and mnesia:start()..
