Error with timesyncd.service after upgrade to 7.0

[MisterY]

Hi,
after upgrading to 7.0.2 I face this errors in the syslog:

Jul 23 12:47:37 r620 systemd[20630]: systemd-timesyncd.service: Failed to set up mount namespacing: /run/systemd/unit-root/: Host is down Jul 23 12:47:37 r620 systemd[20630]: systemd-timesyncd.service: Failed at step NAMESPACE spawning /lib/systemd/systemd-timesyncd: Host is down Jul 23 12:47:37 r620 systemd[1]: systemd-timesyncd.service: Main process exited, code=exited, status=226/NAMESPACE Jul 23 12:47:37 r620 systemd[1]: systemd-timesyncd.service: Failed with result 'exit-code'.

Jul 23 12:47:37 r620 kernel: proc: Bad value for 'hidepid'

This Error is repeated every few seconds.
What's wrong? Everything else is working as I can tell.

you have a container with recent systemd that wants to secure services by further namespacing them. this requires enabling "nesting" on the container, to allow it to further setup child namespaces within the container namespace.

How can I figure out which container is causing this problem?

 

[fabian]

the journal contains the PID of the container systemd, the process tree (ps faxl) should show you which container it belongs too. alternatively, /proc/PIDOFSYSTEMD/cgroup should also give you the container ID.
