Linux 错误：grub在安装Gentoo时安装

我正在笔记本电脑上安装GentooLinux和LUKS、LVM、UEFI、GRUB2和systemd。 我在grub安装中堆栈，它忽略了以下错误

磁盘分区是：

NAME                       MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda                        8:0     0  238.5G  0 disk
sda1                       8:1     0    512M  0 part  /boot/efi
sda2                       8:2     0    238G  0 part
  luksdisk                 252:0   0    238G  0 crypt
    vg1-lv--swap           252:1   0      8G  0 lvm   [SWAP]
    vg1-lv--arch--root     252:2   0     64G  0 lvm
    vg1-lv--gentoo--root   252:3   0     64G  0 lvm   /

我键入的命令是

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

下面是错误消息

Installing for x86_64-efi platform.

我认为发生错误是因为sda1（ESP）是由lvmetad检查的。因此，我将

volume_list={“vg1”}

添加到/etc/lvm/lvm.conf，然后再次点击该命令。这省略了更少的错误消息

Installing for x86_64-efi platform.
File descriptor 3 (/dev/sda1) leaked on vgs invocation. Parent PID 833: grub-install

请帮忙

于2017年1月15日添加

我尝试了一些可能的解决办法

在lvm.conf中添加了以下代码

设备{
:
过滤器=[“r |/dev/sda1 |”]
:
}

结果>>没有任何变化

更改了grub安装

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

Installing for x86_64-efi platform.

File descriptor 3 (/dev/sda1) leaked on vgs invocation. Parent PID 28737: grub-install

  Volume group "luksdisk" not found

在lvm.conf中进行了更改

use_lvmetad = 0

结果>>作为解决方案2的错误消息

No.2和No.3的错误消息显示“未找到卷组”luksdisk，但加密的sda2（luksdisk）不是卷组。

这就是问题的原因吗？
