copied!<p>I'm extremely late to the party, but came across this info in the doc when looking for a solution to the same problem:</p> <blockquote> <p>"The function call mnesia:del_table_copy(schema, mynode@host) deletes the node 'mynode@host' from the Mnesia system. The call fails if mnesia is running on 'mynode@host'. The other mnesia nodes will never try to connect to that node again. Note, if there is a disc resident schema on the node 'mynode@host', the entire mnesia directory should be deleted. This can be done with mnesia:delete_schema/1. If mnesia is started again on the the node 'mynode@host' and the directory has not been cleared, mnesia's behaviour is undefined." (http://www.erlang.org/doc/apps/mnesia/Mnesia_chap5.html#id74278)</p> </blockquote> <p>I think the following might do what you desire:</p> <pre><code>AllTables = mnesia:system_info(tables), DataTables = lists:filter(fun(Table) -> Table =/= schema end, AllTables), RemoveTableCopy = fun(Table,Node) -> Nodes = mnesia:table_info(Table,ram_copies) ++ mnesia:table_info(Table,disc_copies) ++ mnesia:table_info(Table,disc_only_copies), case lists:is_member(Node,Nodes) of true -> mnesia:del_table_copy(Table,Node); false -> ok end end, [RemoveTableCopy(Tbl,'gone@gone_host') || Tbl <- DataTables]. rpc:call('gone@gone_host',mnesia,stop,[]), rpc:call('gone@gone_host',mnesia,delete_schema,[SchemaDir]), RemoveTablecopy(schema,'gone@gone_host'). </code></pre> <p>Though, I haven't tested it since my scenario is slightly different.</p>
