当我得到时,我在mnesia集群数据中有一个坏节点(它不存在):

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

如何从群集中删除它？

我试过了:

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

这是什么意思？我该如何解决？

更新.在从架构中删除节点之前,我们需要在其上停止mnesia

setup_mnesia(Name) ->
    ?VALUE(application:start(mnesia)),
    ?VALUE(mnesia:create_schema([node()|[Name]])),
    ?VALUE(mnesia:create_table(muppet, [
                        {attributes, record_info(fields, muppet)},
                        {disc_copies, [foo@kos13]}])),
    ?VALUE(mnesia:wait_for_tables([muppet], infinity)),
    ok.

结果是

"application:start(mnesia)"= ok

"mnesia:create_schema([node()| [Name]])"= {error,{foo @ kos13,{already_exists,foo @ kos13}}}

"mnesia:create_table(muppet,[{attributes,record_info(fields,muppet)},{disc_copies,[foo @ kos13]}])"= {aborted,{bad_type,muppet,disc_copies,foo @ kos13}}

EDITED,ADDED如果重写两个进程来调用应用程序:在mnesia之后启动:create_schema它吐出"无法安装回退".在当前目录中出现两个文件--FALLBACK.BUP和foo @ kos13131851070846165246847780.
