Hi. I'm getting the subject error on every shutdown in my two Tumbleweed systems. The next lines following the error one are: phenom systemd[1]: Unmounted /datos. phenom systemd[1]: Reached target Unmount All Filesystems. Any hints? Is it harmful?

Hi.

I'm getting the subject error on every shutdown in my two Tumbleweed systems. The next lines following the error one are:

phenom systemd[1]: Unmounted /datos. phenom systemd[1]: Reached target Unmount All Filesystems.

Any hints? Is it harmful?

Not really. It is /run directory which is lost after shutdown anyway, so there is no harm leaving it "dirty". It means some service did not stop and hold this directory busy. That may indicate a bug, and may warrant investigation. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Probably not harmful, but it may be cool to know which service keeps /run busy as it might be shutting down improperly (and maybe loosing data on the process) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Yoink! This goes to the "HowTo Debug Shutdown" file. Thank you very much. IMHO worthy to be in the man-pages of systemd. Have a nice sunday, - Yamaban

The correct way would be shutting down nscd BEFORE plymouthd is started for shutdown-splash. IMHO adding the following line to plymouth-reboot.service should end this. [code] ExecStartPre=/usr/bin/systemctl stop nscd.service [/code] - Yamaban.

By adding that line to the file the output of lsof is empty but the "Failed unmounting Runtime Directory" message remains. In addition, isn't the runtime dir /run/user/<uid>? The output of lsof was /var/run/nscd/group... -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Splash should be displayed as soon as possible, ideally as the very first thing when shutdown is requested. Unfortunately systemd makes it near to impossible.

Agreed, this is a shortcoming. Sadly I've yet to find a combination of ordering hints to apply to both nscd.service and plymouth-reboot.service that give the same functionallity without pushing plymouth-reboot.service even further back. (using After, Before, Conflicts, Requires, Requisite) During SysV init days, I would give nscd a S00nscd link. How do we get nscd.service stopped as one of the first things during shutdown / reboot? I'm running against the wall in this, maybe I do not see the tree before the forest here, but I'm stumped. The ordering I'd like to get is: => shutdown / reboot is called 1. stop nscd 2. start plymouth-reboot.service 3. invoke rc-local.service 4. stop all other services 5. do maschine off / restart - - Or is that wrong? PS: How does one get a dependency / ordering tree from systemd for the shutdown / reboot without doing the "start with debug" dance? "systemd-analyze" is great for boot, but for halt/reboot?? The options --from-pattern=, --to-pattern= do not cover that reliably. - Yamaban.

Or figuring out why plymouthd wants to access the group database in the first place.. or adding a public interface to glibc (I already know about undocumented __nss_disable_nscd()) that permits an application to disable the use of nscd completely.. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
