Bug Description

$ lsb_release -rd
Description: Ubuntu 15.04
Release: 15.04

$ apt-cache policy nbd-client
nbd-client:
  Installed: 1:3.8-4ubuntu0.1
  Candidate: 1:3.8-4ubuntu0.1
  Version table:
 *** 1:3.8-4ubuntu0.1 0
        500 http://ch.archive.ubuntu.com/ubuntu/ vivid-updates/main amd64 Packages

I'm using the nbd-client to mount some raw disk images over the network but starting the nbd-client automatically during bootup does not happen due to the following:

Aug 22 08:54:20 fractal kernel: [ 11.875885] systemd[1]: Found dependency on nbd-client.service/start
Aug 22 08:54:20 fractal kernel: [ 11.875890] systemd[1]: Breaking ordering cycle by deleting job nbd-client.service/start
Aug 22 08:54:20 fractal kernel: [ 11.875891] systemd[1]: Job nbd-client.service/start deleted to break ordering cycle starting with basic.target/start

Meaning after boot, I have to manually run `sudo ndb-client start` every time I want to access these images. Note that this is no diskless system, the images I mount via NBD do not contain the local system, they are totally unrelated.

Description of problem:
With NFS mounts in an fstab it appears that NetworkManager and the autogenerated mount units get into a dependency loop which causes a number of important units to get discarded while trying to resolve the issue.

Version-Release number of selected component (if applicable):
Seen in FC16,17,18

How reproducible:
Every boot with NFS mounts in the fstab

Steps to Reproduce:
1. Try and boot a system with NFS mounts in the fstab.
2.
3.

Actual results:
Several units are deleted and never attempt to stop, several others fail because the root filesystem doesn't get remounted RW until other units time out.

Expected results:
System should come up, remount the root filesystem RW, mount NFS volumes in the fstab without dependency loops or units timing out.

I have this problem as well, or at least a related one. On my system systemd resolves the cycle by disabling NetworkManager, so I have no internet until I systemctl start NetworkManager. Here's the relevant section of the log:

Martin Pitt (pitti) wrote :

This is indeed a too strong/impossible (with NetworkManager) requirement in /etc/init.d/nbd-client:

# Required-Start: $network $local_fs
# Default-Start: S

A service can't simultaneously run in early boot *and* require the network to be up, as that does not work with NetworkManager, connman, or similar "heavy" machinery to bring up the network. It works with ifupdown as that can run sufficiently early in the boot.

If nbd-client really can't work without the network being up, then it needs to run later, i. e. "Default-Start: 2 3 4 5". I don't know this package, would that be reasonable?

The same issue (mostly) was reported in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=796633

Wouter plans to replace the init script with a generator in time for Debian Stretch.

I've asked him to comment on if what pitti suggested is acceptable till then (for Ubuntu Xenial's release).

Hmm. The "2 3 4 5" change doesn't seem to be enough to break the dependency cycle.

I played a bit to see what could break the cycle but I couldn't find it.
By completely removing /etc/init.d/nbd-client, all is fine.
By putting *just* this minimal header:

# Required-Start: $network

...and removing all the other ones, I'm still getting

Alkis Georgopoulos (alkisg) wrote :

I was able to reproduce the issue in Debian Stretch after applying an Ubuntu specific patch to it. So I'm suspecting that Ubuntu's etwork-manager might be involved in this, I've put it to the affects list.

Specifically, by editing Debian's /lib/systemd/system/NetworkManager.service like this:
-After=network-pre.target dbus.service
+Wants=network.target
+Before=network.target

...the dependency cycle error was affecting Debian too.

Tomorrow I'll try the opposite, to revert the Ubuntu .diff from /lib/systemd/system/NetworkManager.service and see if it solves the issue.

Martin Pitt (pitti) wrote :

The main difference between D and U is that Debian's NetworkManager does not enable NetworkManager-wait-online.service by default. This is very likely to create an ordering cycle like this, as this pulls in NetworkManager (which is late boot) into network-online.target, which nbd-client requires.

Revision history for this message
Martin Pitt (pitti) wrote :

+Before=network.target

This is absolutely necessary too, otherwise NetworkManager can be stopped (on shutdown/reboot) before services that require the network to be up get shut down. Thus these services often hang then.

I confirm that by enabling NetworkManager-wait-online.service in Debian Stretch, I started getting dependency cycles.
Replacing "# Default-Start: S" with "# Default-Start: 2 3 4 5" didn't solve the cycles.

Any fixes or workarounds for Xenial?

For now, I removed "Required start: $network" from all the sysvinit services that had it (e.g. /etc/init.d/nbd-client).

@pitti, since
1) wouter isn't planning to fix this upstream soonish (Debian freeze is months ahead),
2) the issue is serious, i.e. people that install nbd-client, then randomly don't have network-manager running after reboots,
3) the included patch is surely better than the existing situation, i.e. it solves the ordering cycle issue by just starting nbd-client later on,

would you approve an SRU for the included patch,
or do you have some better idea on how to handle this?

Thanks!

Martin Pitt (pitti) wrote :

@Alkis: Doesn't that break nbd-client for people who use ifupdown? With that patch it will start much earlier, way before the network is up. Does nbd-client get along with that? I. e. it doesn't fail on startup without a network connection and listens for new network connections coming up?

Alkis Georgopoulos (alkisg) wrote :

Hi Martin,

I don't have access to any systems without network-manager (that's ubuntu-server installations, I imagine?) so I cannot say if it currently works with plain ifupdown or not, and if the patch will break it.

Let's assume the worst, that it now works there and that the patch will break it. In that case we have:

1) The nbd-client sysvinit service will not work as expected; users will notice and hopefully will find this bug report telling them that they need to revert the $network patch.

But now we have:

2) The nbd-client sysvinit service breaking not only itself but other packages as well! Network-manager or other services randomly not starting!
This even affects persons that don't use the nbd-client sysvinit service at all, but just need the nbd-client executable (like LTSP or QEMU users or persons wishing to use nbd-client to temporarily access a remote disk).

I believe that (2) is a lesser evil than (1), which I imagine only affect a minority of the ubuntu-server installations that also happend to need the nbd-client service.

In any case, if this won't be fixed for Xenial, let's please mention it in this bug report, so that we develop a workaround in LTSP, for all LTSP users that need it immediately.

Thanks a lot,
Alkis

There is other bug 1717459 - about "Job local-fs.target/start deleted to break ordering cycle starting with networking.service/start".

All these bugs make system with systemd useless (does not matter on desktop, in cloud, or on server).

There are many potential affected packages I have no insight, but for nbd this should be fixed since 1:3.14-1 by upstream now providing a native systemd service.

That means >=Zesty should be fixed in that regard.
Not sure on backporting that - one would need to check the potential further context that needs to go back to Xenial, but that might be the proper solution that one might want to try.

Note that the workaround here is to edit the file in /etc/init.d/ manually and remove the circular dependency. If somebody familiar could detail the exact edit here for the benefit of others, that would be appreciated.

Local changes to /etc will be preserved on package upgrades.

Since there is a workaround, this issue is not critical. See https://wiki.ubuntu.com/Bugs/Importance for definitions. I'm editing the subject line of the bug to avoid users getting unrealistic expectations of an imminent fix.

If somebody would like to volunteer debdiffs that we can upload to fix this, please do. nbd is already fixed in newer releases, so see https://wiki.ubuntu.com/StableReleaseUpdates#Procedure for what you need to do for stable releases.

I don't understand what exactly is the problem with the other packages that others have added tasks for. It would be helpful if someone could explain each one using the form of a normal bug report (steps to reproduce, etc). In particular, it is not helpful to assume that the same error message means that it is the same bug, since if it turns out not to be the case, then it just leads to a whole bunch of confusion in the same bug. If in doubt, please use separate bugs to track different initially.
