Mnesia broken?

Hi all,

I can't add a new Mnesia node to an already runnning set
of Mnesia nodes, i.e. inherit the db schema on the new

It used to work (doesn't it always ;-), or is it just me
having a bad day?

Is this feature broken in Mnesia in 47.4.1?


The bug(?) in a simple example:

-- Start 

[]$ erl -sname x
Erlang (JAM) emulator version 47.4.1
Eshell V47.4.1  (abort with ^G)
()1> mnesia:create_schema([node()]).
()2> mnesia:start().

-- Start 

[]$ erl -sname y -mnesia extra_db_nodes \[\]
Erlang (JAM) emulator version 47.4.1
Eshell V47.4.1  (abort with ^G)
()1> mnesia:start().

-- Add  to 's mnesia context, i.e. inherit schema.

()4> mnesia:change_table_copy_type(,disc_copies).

Ohps!  hangs forever...

-- Ohps! Oh no  crashes...
