All LVM commands give me the error /run/lvm/lvmetad.socket: connect failed: No such file or directory. I Googled this error and found only postings related to Grub and Grub-install.

wish to get rid of those errors

If you are using lvm and systemd do:

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

BTW this is grub related as well. I think grub gets kernel parameter root from /run/lvm/lvmetad.socket.

Wasn't patient to test all this in detail as it worked out to function. Please someone correct me if I'm wrong.

Edit: This is only relevant for systems using systemd for init. If you are on older ubuntu you mnight be using upstart instead and on other systems openrc.

  • I did all those commands, none gave me any error. But when I have chrooted and try to update my grub using grub2-mkconfig -o /boot/grub2/grub.cfg, it still returns me the error /run/lvm/lvmetad.socket: connect failed: No such file or directory.

Assuming you're running Linux, in /etc/lvm/lvm.conf set:

use_lvmetad = 0

Stop LVM prior to doing that: /etc/init.d/lvm stop. Make the change and restart LVM: /etc/init.d/lvm start.

EDIT: I realize there's no such file or directory on Linux Mint, hence neither on Debian nor Ubuntu, shall I deduce. If you don't have such a service, just reboot the computer.

Hint: add your operating system in the tag list.
