Is /usr included directly during booting? Show your /etc/ fstab. If you manually mount and unmount does it work then?

shm               /dev/shm     tmpfs   nodev,nosuid,noexec  0 0


my mounting configurations hasnt changed since a long time.
i dont think the problem is related to it.

Have you closed all programs using files on /usr before shutdown? Are there any mounts below /usr that are not listed in /etc/fstab? What version is the systemd tool that produces the error message? When was it last updated?

please unmount and mount to test


Code:
#umount /usr
#mount /dev/sdx /usr

We will check its all right if the system booted

Hi

@Hu : under /usr there is only another partition used for portage (/dev/sda9 -> /usr/portage) which is mentionned in fstab, but i dont think the problem is related to this partition.
The version of systemd : Installed versions: 232(12:41:55 19/11/2016)

@michi-monster : i cant unmount /usr as all the libraries for the initial process is used there (systemd).

I have test with an old version of systemd (stable release226-r2) same problem without logs

thanks for your suggestions.

I suspected that would be the problem. You need to stop that systemd process before shutdown, so that the libraries are not in use. If that systemd process is sufficiently critical to normal operation, it may not be possible to stop it before shutdown.
