错误“/run/lvm/lvmetad.socket：连接失败：没有这样的文件或目录” - 但与 Grub 无关

Question

所有 LVM 命令都给我错误/run/lvm/lvmetad.socket: connect failed: No such file or directory。我在谷歌上搜索了这个错误，只找到了与 Grub 和 Grub-install 相关的帖子。

希望摆脱这些错误

Answer 1

如果您使用 lvm 和 systemd，请执行以下操作：

systemctl enable lvm2-lvmetad.service
systemctl enable lvm2-lvmetad.socket
systemctl start lvm2-lvmetad.service
systemctl start lvm2-lvmetad.socket

顺便说一句，这也与 grub 相关。我认为 grub从 /run/lvm/lvmetad.socket获取内核参数根。

没有耐心详细测试所有这些，因为它可以正常工作。如果我错了，请有人纠正我。

编辑：这仅与使用 systemd 进行 init 的系统相关。如果您使用的是较旧的 ubuntu，您可能会在其他系统上使用 upstart 和 openrc。

Answer 2

假设您正在运行 Linux，则/etc/lvm/lvm.conf：

use_lvmetad = 0

停止LVM之前这样做：/etc/init.d/lvm stop。进行更改并重新启动LVM： /etc/init.d/lvm start。

编辑：我意识到 Linux Mint 上没有这样的文件或目录，因此无论是在 Debian 还是 Ubuntu 上，我都应该推断。如果您没有这样的服务，只需重新启动计算机。
