GRUB“核心图像中可能缺少某些模块”警告

Modified on: Tue, 27 Aug 2019 14:20:02 +0800

一台硬盘从我的RAID中崩溃,我添加了一个新硬盘
现在我想将GRUB安装到新硬盘上:使用grub-install /dev/sdb
我收到了这些警告:

Installing for i386-pc platform.
grub-install: warning: Couldn't find physical volume `(null)'. Some modules may be missing from core image..
grub-install: warning: Couldn't find physical volume `(null)'. Some modules may be missing from core image..
Installation finished. No error reported.

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?

更新强>

由于它只是一个警告,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。
