Hi, After last system updating I get this 'WARNING' output while running grub2: grub2-mkconfig -o /boot/grub/grub.cfg Generating grub configuration file ... Found linux image: /boot/vmlinuz-4.1.12-gentoo Found linux image: /boot/vmlinuz-4.0.5-gentoo /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad. Falling back to internal scanning. Found Windows Vista (loader) on /dev/sda1 System is working ok but afraid it can cause to a real problem. I get this issue in another similar machine.

*** Bug 574676 has been marked as a duplicate of this bug. ***
I updated from sys-fs/lvm2-2.02.116 to -r4 and have the same warning with `grub-mkconfig`. I have it with `rc-update -u` too, so it's more general: # rc-update -u * Caching service dependencies ... File descriptor 3 (pipe:[5196152]) leaked on lvm invocation. Parent PID 17753: /bin/sh /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad. Falling back to internal scanning. I'm not using LVM directly. cryptsetup depends on it through Portage (for my LUKS partitions), but from what I understand, it's not even starting lvm/lvmetad initscripts, which also are not in my `rc-update show`. I have not enabled LVM in my genkernel.conf file either. I have not tested a reboot yet, to check if it's just an harmless warning... An elog message in lvm2 ebuild mentions restarting udev, but it changes nothing. If I downgrade back to lvm2-2.02-116, there is no more warning message with `rc-update -u`. ... but the warning message is still here with `grub-mkconfig -o /boot/grub/grub.cfg`... I did update from sys-boot/grub-2.02_beta2-r8 to -r9 too at the same time as lvm2... ... but if I downgrade back to -r8, I still have the warning... I'm pretty sure I ran `grub-mkconfig` without this warning a few months back though... Maybe I was still using -r7 at that time, but it's not in Portage anymore to easily test downgrading... I had lvm2-2.02.109 at that time too...

That warning is coming from os-prober, which gets called by /etc/grub.d/30_os-prober.

Your LVM setup is currently wrong and you need a clean boot.
I think you just need to change use_lvmetad to 0 in /etc/lvm/lvm.conf to make this warning go away.
This is lvm related bug. In clean lvm setup init.d/lvmetad don't create /run/lvm/ dir for /run/lvm/lvmetad.socket. `mkdir /run/lvm/` solved the problem We have to fix it in init.d/lvmetad or send to upstream?
(In reply to Vladimir Varlamov from comment #6) Sounds like a separate bug report to me.
What is the status with 1.71?
