Arch GRUB在非LVM磁盘上要求/run/lvm/lvmetad.socket

我正在基于ArchWiki设置过程运行此脚本。在GRUB配置步骤中失败

我在具有1 GB内存的VMware Player中使用archlinux-2013.12.01-dual.iso，内存sda为810 MB。我还在主机上安装了CIFS共享。

# DEV=sda
# PART=sda1
# echo "1,,L,*" | sfdisk /dev/$DEV
# mkfs.ext3 /dev/$PART
# mount /dev/$PART /mnt
# pacstrap -i /mnt base 
# genfstab -U -p /mnt >> /mnt/etc/fstab
# arch-chroot /mnt 
# pacman -S grub
# pacman -S os-prober
# grub-mkconfig -o /boot/grub/grub.cfg

我得到：

我刚才遇到了同一问题，发现了另一个解决方法。基本上，它涉及使主机/run目录对来宾可用。

首先，我们将/run其安装在访客可以访问的位置。我将假设您的安装分区已安装在/mnt

mkdir /mnt/hostrun
mount --bind /run /mnt/hostrun

然后，我们将chroot插入guest虚拟机，然后将host的主机挂载/run/lvm到guest虚拟机的/run

arch-chroot /mnt /bin/bash
mkdir /run/lvm
mount --bind /hostrun/lvm /run/lvm

然后grub-mkconfig，您可以运行并且grub-install没有任何LVM错误。如果要使用 LVM 进行安装，这也使命令能够正常运行。

完成后，请记住在chroot umount /run/lvm之前要进行exit。

经过@guest触发的研究之后，我发现grub-mkconfig辅助脚本中存在一个明显的错误，该错误/etc/grub.d/10_linux使后备initramfs GRUB条目与GRUB子菜单系统不兼容。由于后备initramfs的用法非常特定于Arch和派生类，因此上游不支持 grub-mkconfig。最终修复仍在进行中。查看关于bugs.archlinux.org的更多详细信息

因此，一种临时的解决方法是通过添加以下内容来禁用GRUB中的子菜单：

GRUB_DISABLE_SUBMENU=y

到/etc/default/grub。

不幸的是，通过禁用子菜单，我仅避免了提出的第二个错误grub-mkconfig。

因此，具有：

# arch-chroot /mnt grub-mkconfig -o /boot/grub/grub.cfg

我仍然得到：

我从未安装过LVM分区/驱动器，并且从您的问题中可以看到，我对系统进行了分区和格式化。无论如何，在修复GRUB错误之后，我同时尝试了两种方法：

systemctl start lvmetad

和

systemctl start lvmetad.service

我又跑pacstrap了，没有成功。

当前错误不严重，因为

arch-chroot /mnt grub-install --target=i386-pc --recheck /dev/$DEV

顺利进行，我可以从这里启动$DEV。

我遇到了同样的问题，但是我找到了适合我的解决方案：只需删除os-prober。

将GRUB_DISABLE_SUBMENU = y行添加到/ etc / default / grub可能会有所帮助

对于第一个错误消息，grub无法连接到LVM元数据守护程序，请尝试以root用户身份运行此命令（它将启动它）：

systemctl start lvmetad

第二个尝试尝试增加分配给VM的RAM 512M，然后再次运行grub。
