Remove not_exist_already node from mnesia cluster(scheme)

I have a bad node (it doesn't exist) in the mnesia cluster data when I get:

> mnesia:system_info(db_nodes)
[bad@node, ...]

How do I remove it from the cluster?

I tried:

> mnesia:del_table_copy(scheme, bad@node).
{aborted,{not_active,"All replicas on diskfull nodes are not active yet"...

What does this mean? How can I fix it?

Update. Before remove node from schema we need to stop mnesia on it
