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

所有LVM命令都会给我错误/run/lvm/lvmetad.socket: connect failed: No such file or directory。我用Google搜索了此错误，仅发现与Grub和Grub安装相关的帖子。

希望摆脱那些错误

如果您使用的是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g有关。我认为grub 从/run/lvm/lvmetad.socket 获取内核参数根。

在工作正常时，耐心耐心地对所有这些进行详细测试。如果我错了，请有人纠正我。

编辑：这仅与使用systemd进行初始化的系统有关。如果您使用的是较旧的ubuntu，则可能会改用upstart和其他系统上的openrc。

假设您正在运行Linux，请按以下步骤操作/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，因此在Debian和Ubuntu上都没有，我应该推断。如果您没有这样的服务，只需重新启动计算机即可。
