我是否必须担心“错误：多余的 RAID 成员”？

Question

当update-grub在新安装的 Ubuntu 12.04 上使用旧软件 RAID (md) 运行时，我得到：

error: superfluous RAID member (5 found).
error: superfluous RAID member (5 found).
Generating grub.cfg ...

如果消息会说warning: ...，我会不那么担心，但既然它说error: ...我想知道问题是什么。

# cat /proc/mdstat

我需要担心还是无害？

顺便说一句：忽略 Debian 5.0.9 的提及，这是以前安装的系统，将被覆盖。它/dev/md2实际上在。

正如Fussy Salsify在这里提到的，这似乎是一个RAID 阵列中带有备用设备的 update-grub 脚本的错误。正如这里提到的，已经应用了一个补丁，应该会在某个时候出现在 Ubuntu 中。

Boyd Stephen Smith Jr.说他认为这个错误报告在这里可能只是装饰性的，而Vladimir '?-coder/phcoder' Serbinenko提交了一个补丁，似乎只是将错误报告更改为“未实施备件”。

启动板 ( #816475 ) 上还有一个错误报告，以及可能涉及更改分区的解决方法。这个错误的重要性在启动板上尚未确定，但看起来它给Björn Tillenius带来了一些无法升级/安装 grub 的真正问题。所以看起来你应该小心。
