一个硬盘从我的RAID崩溃,我添加了一个新的硬盘.
现在我想将GRUB安装到新硬盘上：使用grub-install / dev / sdb.
我收到这些警告：

我收到这些警告：

在update-grub2上,我得到：

我使用apt-get install –reinstall重新安装了两个内核,但这些错误/警告仍然存在.
有谁知道我怎么能摆脱它们？
更新：
因为它只是一个警告,而不是错误(并且GRUB必须仍然在sda上)我重新启动了系统.
系统启动并且警告消失.
我不知道触发警告的原因.
我在重建降级的SW-RAID阵列时遇到了同样的问题,并在另一个网站上绊倒了这个问题：
原文链接：https://www.f2er.com/ubuntu/348794.html出现警告的grub-2.00源代码位于./grub-core/disk/diskfilter.c并有此评论：
/* TRANSLATORS: This message kicks in during the detection of which modules needs to be included in core image. This happens in the case of degraded RAID and means that autodetection may fail to include some of modules. It's an installation time message,not runtime message. */
(摘自https://bbs.archlinux.org/viewtopic.php?id=160785)
换句话说,当您的RAID阵列性能下降时会发生这种奇怪的错误,并且一旦阵列正常运行,它就会消失(在您的情况下会这样做).
当我的RAID阵列最终完成同步时,错误在update-grub和grub-install上都消失了.
