我正在笔记本电脑上安装带有 LUKS、LVM、UEFI、GRUB2 和 systemd 的 Gentoo Linux。我堆叠在 grub-install 中，省略了以下错误。

磁盘分区为：

NAME                       MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda                        8:0     0  238.5G  0 disk

    vg1-lv--gentoo--root   252:3   0     64G  0 lvm   /

我输入的命令是

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=gentoo_grub --recheck

并且错误消息如下。

我认为发生错误是因为 lvmetad 检查了 sda1(ESP)。所以我添加volume_list = { "vg1" }到/etc/lvm/lvm.conf，然后再次点击命令。这省略了更少的错误消息。

请帮忙！

我尝试了一些可能的解决方案。

  1. 将以下代码添加到 lvm.conf
devices { 
    :
    filter = [ "r|/dev/sda1|" ]
    :
}

结果 >> 没有任何变化

  1. 更改了 grub-install

    LVM_SUPPRESS_FD_WARNINGS=1 grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=gentoo_grub --recheck

结果 >> 错误消息更改如下

  1. 在 lvm.conf 中进行了更改

    use_lvmetad = 0

结果 >> 错误消息作为解决方案 2

No.2 和 No.3 的错误信息显示“未找到卷组“luksdisk”，但加密的 sda2 (luksdisk) 不是卷组。这是问题的原因吗？？？
