我是否需要担心“错误：多余的RAID成员”？

在update-grub新安装的具有较旧软件RAID（md）的Ubuntu 12.04上运行时，我得到：

error: superfluous RAID member (5 found).
error: superfluous RAID member (5 found).

如果消息会显示warning: ...，我会担心一些，但是由于它显示了消息，所以error: ...我想知道问题是什么。

我需要担心还是无害？

顺便说一句：忽略了Debian 5.0.9的提法，它是先前安装的系统，将被覆盖。它/dev/md2实际上在。

如Fussy Salsify 在此处所述，这似乎是其中一个RAID阵列中具有备用设备的update-grub脚本的错误。如此处所述，已经应用了补丁，并且应该在某个时候安装到Ubuntu。

博伊德斯蒂芬·史密斯小说，他认为这个错误报告可能只是化妆品在这里和弗拉基米尔“φ编码器/ phcoder” Serbinenko提交了一个补丁，似乎只是改变为“备用没有实现”错误报告。

另外，在启动板（＃816475）上有一个错误报告，以及可能的解决方法，其中涉及更改分区。这个错误的重要性尚未在启动板上确定，但看起来它给BjörnTillenius造成了一些无法升级/安装grub的实际问题。所以看起来您应该小心。

在升级grub期间和在启动PC时，我在ubuntu 12.04上均出现此错误，但这是由于我这一边的配置错误：

我在使用RAID1的mdadm配对的两个磁盘上有两个分区。在一个磁盘崩溃后，我将其替换并添加了一个新磁盘，但是在某些时候输入命令添加分区（mdadm --manage /dev/md... -a /dev/sd...）时，我错误地添加了整个磁盘（/ dev / sdb）而不是分区（/ dev / sdb1）的一部分/ dev / md1。我删除了整个磁盘并正确添加了分区，并且/ proc / mdstat看起来一切正常，所以我以为我结束了。

但是，重新启动后出现“错误：多余的RAID成员（找到2个）”。在我的屏幕上短暂出现，并且RAID阵列没有用新磁盘的分区重建。

我必须将/ dev / sdb（磁盘）的超级块归零，mdadm --zero-superblock /dev/sdb以对其进行修复，该超级块还具有“错误：多余的RAID成员（找到2个）”的权限。都来自启动和update-grub。
