Description Jan Stodola 2016-06-08 12:39:45 UTC

Description of problem:
When verifying bug 1338759 I noticed the following warning when rebooting the system:

[   42.401813] systemd-shutdown[1]: Sending SIGKILL to remaining processes...
[   42.404672] systemd-shutdown[1]: Unmounting file systems.
[   42.406297] systemd-shutdown[1]: Unmounting /run/netns/namespace.
[   42.407469] systemd-shutdown[1]: Unmounting /run/netns/namespace.
[   42.408819] systemd-shutdown[1]: Unmounting /run/netns.
[   42.474532] systemd-shutdown[1]: Unmounting /run/netns/namespace.
[   42.475970] systemd-shutdown[1]: Unmounting /run/netns/namespace.
[   42.477191] systemd-shutdown[1]: Could not unmount /run/netns/namespace: Invalid argument
[   42.478824] systemd-shutdown[1]: Not all file systems unmounted, 1 left.

Version-Release number of selected component (if applicable):
systemd-219-19.el7
dracut-033-360.el7_2.1

How reproducible:
always

Steps to Reproduce:
1. install RHEL-7.2 GA with root file system on LVM
2. update dracut to version 033-360.el7_2.1
3. Add a network namespace:
# ip netns add namespace
4. # systemctl reboot

Actual results:
warning message on reboot:
...
systemd-shutdown[1]: Could not unmount /run/netns/namespace: Invalid argument
...

Expected results:
no warning message

Additional info:
From IRC conversation:
<harald> systemd should probably delete all network namespaces on shutdown
