Bug#766943: systemd: server no longer gets networking after switching to systemd

[Christoph Anton Mitterer]

Package: systemd
Version: 215-5+b1
Severity: important


Hi.

Tonight I switched my last server still running with sysvinit to
systemd, since I've experience no major problems with it on my other
systems.

That server however, didn't come up anymore (i.e. not even pinging
back).
I've sent a Ctrl-Alt-Del event via the hosting company's web interface,
and it actually came back and I could log in.

The logs from syslog didn't show much interesting stuff, only that
apache httpd (which runs on that node) couldn't bind to the IPv4
addres.


I've rebooted another time then (and several more times since then), but
now it's back to no booting (or rather said: no networking - at least
the first time where it didn't work, syslog showed, that it actually
started up, and also got a clean shutdown).


I can't say much about the system or logs right now,... it's a physical
machine, IPv4 and v6 addresses, brought up via ifupdown using allow-auto
for eth0 in /e/n/interfaces.
It uses mdadm with a RAID1.

The only other "special" thing that I remember is, that I use
rootdelay=10
as a kernel parameter.
TBH, I forgot why, but there was something that the disks were detected
too lated and the initramfs could never mount the rootfs.
But that shoudln't affect systemd, right?




I write the bug already now, since it's really complicated to get
access to the server by other means,... hetzner (the company) does provide
some KVM interface, but that's implemented quite insecurely and it costs
when one needs it for a longer time.

So it would be great if you could already tell me in advance which logs
to look for, and which things to test.

Obviously I'll set systemd.log_level=debug at the kernel command line...
anything else?


Cheers,
Chris.
