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
node.

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

Is this feature broken in Mnesia in 47.4.1?

/Jocke

The bug(?) in a simple example:

-- Start x_at_kaja

[jocke_at_kaja]$ erl -sname x
Erlang (JAM) emulator version 47.4.1

Eshell V47.4.1 (abort with ^G)
(x_at_kaja)1> mnesia:create_schema([node()]).
ok
(x_at_kaja)2> mnesia:start().
ok

-- Start y_at_kaja

[jocke_at_kaja]$ erl -sname y -mnesia extra_db_nodes [x_at_kaja]
Erlang (JAM) emulator version 47.4.1

Eshell V47.4.1 (abort with ^G)
(y_at_kaja)1> mnesia:start().
ok

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

(x_at_kaja)4> mnesia:change_table_copy_type(schema,y_at_kaja,disc_copies).

Ohps! x_at_kaja hangs forever...

-- Ohps! Oh no y_at_kaja crashes...
