[erlang-questions] Mnesia table replication

[Dana.RUBINO@REDACTED]

Thanks Chandru - that's been a great help.

I ran mnesia:change_config(extra_db_nodes, ['dan@REDACTED']).

The create table command now works - this will now I assume give me replication and conflict resolution between these two nodes?

Thanks,
Dan

Ok I have given it a go with a test table as such:

-module(test).
-record(test, {id, name}).

test() ->
    mnesia:create_table(test, [{attributes, record_info(fields, test)}, {disc_copies, ['dan@REDACTED']}]).


I then create two local nodes on the same machine and start up Mnesia on each.

When looking at each node via the appmon I can see Mnesia has started - I can also ping one node from another.

When however I run the test method on one node expecting it to create a replica on the other I get the following error:

{aborted,{not_active,test,dan@REDACTED}}

Have I missed a step here perhaps?


Is the schema shared across both the nodes? What does mnesia:system_info(db_nodes) return?
