[Bug 2022030] Re: vlan network device lost after the ubuntu 23.04 install complete

[mayijie]

Hi Danilo,

I tried your steps on comment #34, but no lucky, from the systemd-
networkd log, it looks the same issue.

1) upgrade to mantic
> 
ubuntu at a257ubut03:~$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu Mantic Minotaur (development branch)
Release:	23.10
Codename:	mantic


2) reboot and check if the problem persists

Yes, the problem persists.


3) if the problem is still there, upgrade systemd to the version in mantic-proposed (which is 253.5)
>
ubuntu at a257ubut03:~$ dpkg -l | grep systemd
ii  systemd               253.5-1ubuntu1            s390x        system and service manager
ii  systemd-dev           253.5-1ubuntu1            all          systemd development files
ii  systemd-hwe-hwdb      252.4.3                   all          udev rules for hardware enablement (HWE)
ii  systemd-resolved      252.5-2ubuntu3            s390x        systemd DNS resolver
ii  systemd-sysv          252.5-2ubuntu3            s390x        system and service manager - SysV compatibility symlinks
ii  systemd-timesyncd     252.5-2ubuntu3            s390x        minimalistic service to synchronize local time with NTP servers

4) do the same tests to see if the problem is still present
>
Yes, the vlan interface disappeared after 'sudo reboot' and can be showed up after 'sudo systemctl restart systemd-networkd'. I'll attach the systemd-networkd log and the timestamps after systemd upgraded are:
Jul 18 08:31  -> reboot the os
Jul 18 08:36  -> restart systemd-networkd service

Thanks.

  VERSION="23.04 (Lunar Lobster)"

  System hardware: IBM LinuxONE

  Details:
  During the installation, I set up and actived a vlan device, after the installation, when I login the OS, the vlan device disappeared, I opened the '/etc/netplan/00-installer-config.yaml', double checked the config file, the vlan1300 is existing, and then when I 'netplan apply' to perform the configuration, an error message shows up, 

  "[?2004hubuntu at ibm:~$ 
  "sudo netplan apply
  "[?2004l
  "Cannot call openvswitch: ovsdb-server.service is not running.

  And during the boot stage, the systemd-networkd-wait-online.se tart
  running message shows a lot in the log, not sure these are related.

  "M[K[    [0;31m*[0;1;31m*[0m] Job systemd-networkd-wait-online.se  tart running (1min 11s / no limit)

  "M[K[[0;1;31m*[0m[0;31m*    [0m] Job systemd-networkd-wait-online.se  tart running (1min 15s / no limit)

  Attached the operating system boot log.

  Thanks.
