This is an inofensive message and you should not worry about it.
If you do 'man lvmetad' you'll find that it is a daemon that caches disk metadata. If this daemon is not available, lvm will read the metadata from the disk. This may be a problem with very complex systems with hundreds of volumes, but it is not for a desktop.
Every message that says it has been solved by touching grub or after installing some packages, has probably solved by upgrading the system and recreating the grub configuration.
This is a very very low priority bug and was there in Ubuntu and Debian for a while. Probably will dissapear in a upgrade without doing anything.
I've got that message for a while and without any adverse condition.
People complaining to be unable to login are being affected by another error and should continue checking the logs to find it.

Thanks to @Kyle in this thread, you can stop this blocking your interactive ttys from appearing with the following:
I managed to resolve this for my machines by adjusting the grub configuration like so:
In
/etc/default/grub
, change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
toGRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
Then add this line:GRUB_TERMINAL_INPUT="console serial"
Run sudo update-grub and reboot for the changes to take effect.

This just sends logs somewhere else, maybe impacting useful log reporting. Solves nothing regarding what is being logged. – Telegrapher Sep 26 '18 at 22:23

In the thread you mention they solve a video issue by enabling nomodeset, it is absolutely unrelated to the messages. – Telegrapher Sep 26 '18 at 22:28

You are correct, but the I believe the problem OP is experiencing is absolutely unrelated to the messages, beyond the messages appearance being a symptom. The problem is that the TTY this message appears in is non-interactive (ie the user cannot login). What I believe OP is asking for, is an interactive tty to appear immediately instead of having to manually switch to one using ctrl-alt-f[1-7] every time they boot. Now, fair enough I may be reading more into the issue than required, however this question ranked highly in the google results when I was trying to resolve the issue detailed – cleary Oct 03 '18 at 01:41
