lvm2 service slows boot

Tellum · 01-20-2016, 05:12 AM

Hello I am using OpenSUSE Tumbleweed. After upgrading to kernel 4.4.0.1 from 4.3.3.6. boot and shut down are taking a lot of time. Seems it is because of a cron job about LVM2, but I do not use it.

Doing:

Code:

systemctl mask lvm2-activation-early.service
systemctl mask lvm2-activation.service

(According to this recomendation: https://forums.opensuse.org/showthre...-DVB-S2-driver )
And

Code:

systemctl disable lvm2-lvmetad.service lvm2-lvmetad.socket
systemctl stop lvm2-lvmetad.service lvm2-lvmetad.socket

(according to this: http://lists.opensuse.org/opensuse/2.../msg00372.html)
Not solves the problem. In Yast->services: lvm2-activation-net,
lvm2-lvmetad, and lvm2-monitor are dishabled and inhabilited. The boot log shows:

Code:

http://pastebin.com/qq2zeqkY

In the power off it says that could not unmount the linux partition because /var/run is busy.

This coomand

Code:

systemctl status lvm2-activation-net.service

shows:

Code:

lvm2-activation-net.service - Activation of LVM2 logical volumes
   Loaded: loaded (/etc/lvm/lvm.conf)

  Process: 1127 ExecStartPre=/usr/bin/udevadm settle (code=exited, status=1/FAILURE)

This command

Code:

shows:

Code:

         16.813s dev-sda7.device

           884ms home-windows.mount
           847ms systemd-tmpfiles-clean.service
           etc

But if instead of starting with new kernel (4.4.0.1) I select the previous (4.3.3.6) then it is working:

Code:

http://pastebin.com/TSagp0GL

And

Code:

systemctl status lvm2-activation-net.service

output is:

Code:

systemd-udev-settle.service
   Loaded: masked (/dev/null)
   Active: inactive (dead)

Boot and shutdown are fast again. And returning to new installed kernel (4.4.0.1) drives to previous problem. (And every time I change kernel I reinstall nvidia driver).

My fdisk -l its:

Same problem here....
Activation of LVM2 logical volumes takes too long and it doesn't shutdown because it can't umount the /var/run partition because it is busy.
If i start the system with the previous kernel (4.3.x) everything works ok.
Did you find a way to fix this?

OpenSUSE Tumbleweed 4.4.0.2-default

No luck sorry. I tried with a fresh installation and problem appears inmediately booting the first time. Seems that our hardware is not well supported but no problem, there are many cool distros out there.

Here: https://forums.opensuse.org/showthre...-kernel-update
infinity-it said that for him worked this:
# systemctl mask systemd-udev-settle.service
# systemctl mask lvm2-activation-net.service

I can not try because already changed distro. :P So try it if you not done it already and then if you still want a cuting edge release as Tumbleweed (and you do not hate gnome) I recommed Fedora, last version 23 is working without problems

.

If this code works for you let me know and I will mark my 3 threads about this solved.

The trick fixed the slow boot, but not the /var/run locked at the shutdown/reboot.
Actually /var/run is a partition mounted in ram (tmpfs) so... is it really mandatory to unmount it before shutdown?
