[Solved] systemd daemon-reload hang - netplan bridge mul net daemons

Recently I noticed that after updating my system (sudo pacman -Syu) when the post install task (reloading system manager configuration...) ran that there was a noticeable delay of over 1 minute. I determined that this pacman hook called systemctl daemon-reload and if I ran this I got the same delay. I also noticed the same delay if I ran either enable or disable. For example:

[root@spike ~]# time systemctl disable postgresql.service
Removed "/etc/systemd/system/multi-user.target.wants/postgresql.service".

real	1m0.507s
user	0m0.009s
sys	0m0.004s

[root@spike ~]# time systemctl enable postgresql.service
Created symlink /etc/systemd/system/multi-user.target.wants/postgresql.service -> /usr/lib/systemd/system/postgresql.service.

real	1m0.254s
user	0m0.004s
sys	0m0.009

In both cases the message was displayed immediately. I could not find anything with journalctl. Any ideas?

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

Systemd has been updated. As a core component it probably needs a reboot to finish properly.
Also check that '/etc/mkinitcpio.conf.pacnew' is solved (don't forget to regenerate initramfs).

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

Thanks but it made no difference. My system was updated but I still regenerated initramfs. Some other weirdness - I have a laptop which has the same packages installed and it does not exhibit the problem; and when the system is hanging on an enable/disable I can open another terminal window (Gnome) but I cannot even enter "ls" in the window.

Maybe do a fsck on the drive.
What happens when you create the link manually?
Check the drive/filesystem for free space (especially free inodes).

In that case, only if you are not both an expert and infallible would it be worthwhile to post the journal. wink
People are likely to have more ideas if you provide them with the information. Presumably, you're asking because you hope somebody will spot something you haven't. The less you provide, the less there is to spot.

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

fsck on the drive showed no errors.

creation and removal of the link returns instantly.

free space on the drive looks good:

[ed@spike ~]$ stat -f /dev/nvme0n1p2
  File: "/dev/nvme0n1p2"

If I re-run the tests:

[root@spike ~]# date

[root@spike ~]# time systemctl disable postgresql.service
Removed "/etc/systemd/system/multi-user.target.wants/postgresql.service".

user	0m0.012s
sys	0m0.003s
[root@spike ~]# date
Sun Nov 27 09:18:13 AM CST 2022

I get the following journal for that time period:

Read that output again. You can see it isn't telling you anything about your root partition: *all* of the blocks are free and the file system type is tmpfs. 

df -h
lsblk -f

will tell you how much space you have, though I don't think it will report inodes.

The journal snippet you posted shows nothing about manipulating the postgresql.service.

If my understanding of systemctl enable/disable is correct then all it should be doing in creating and removing a link and thus there should be no journal entries for that - which there are not. Also if all systemd is doing in creating/removing a link why can I do it instantly but systemd hangs for almost a minute *after* displaying what it has done.

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

Try an 'strace -v -f -s 256 -o /tmp/strace.log systemctl disable postgresql.service' and post the strace.log file. Let it run for the minute until it ends properly.

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

systemctl will IPC talk to the damon and we already know that the dameon-reload is the slow part.

systemctl log-level # to note the original loglevel
systemctl log-level debug
systemctl daemon-reload
systemctl log-level info # i guess

Then inspect the system journal

Also if all systemd is doing in creating/removing a link why can I do it instantly but systemd hangs for almost a minute *after* displaying what it has done.

man systemctl wrote:

       --no-reload
           When used with enable and disable, do not implicitly reload daemon configuration after
           executing the changes.

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

The strace log can be found at: https://0x0.st/o0bY.log

And the journal for running systemctl in debug mode can be found at: https://0x0.st/o0bg.txt

Thanks for the tip about --no-reload. I tried it and enable/disable worked instantly. I definitely need to read the man pages more closely.

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

Nov 28 09:32:29 spike systemd[2550]: /usr/lib/systemd/system-generators/systemd-system-update-generator succeeded.
Nov 28 09:33:29 spike systemd[2550]: /usr/lib/systemd/system-generators/netplan succeeded.

From the debug output it looks like there're multiple network daemons:

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Nope.
Temporarily get rid of https://archlinux.org/packages/communit … 4/netplan/ and see what happens.

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

Thank you. That fixed the problem. daemon-reload returns immediately. I installed netplan to create a network bridge so that I could have my kvm guests on the same subnet as my host. It's weird since I installed netplan and created the bridge back on 9/18 but this problem only started occurring several weeks ago.

I was able to start the bridge with virsh and run a VM but I noticed that after a certain amount of time virsh showed the bridge becoming inactive by itself. I can easily do without the bridge if there is no way around it. Please let me know what you think.

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

netplan was updated Aug 22, 2022 - you could try to downgrade it to 0.104-1 from the ALA (or your cache)
I've never used netplan and no idea how it's related to a bridge.

https://wiki.archlinux.org/title/Network_bridge and configure your VM to use the bridge device (eg. br0), https://wiki.archlinux.org/title/Libvirt#Networking ??

Edit: either way please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
And in this case, maybe even mention the cause in the subject - netplan seems fringe (I wasn't even aware that it exists…)

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

I'll clean-up my networking setup and check into the 2 links you mentioned. I'll admit that I got lazy and googled how to get the guests on the same subnet as the host. If you're curious - https://serverfault.com/questions/10754 … s-the-host. Thanks again.

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

I appreciate the help on figuring out this 60s delay issue.  During that 60s a lot of things are blocked, even things like loading of web pages from that server, so that delay makes server administration during business hours a real problem.

For those like me who are using Arch on a VM:  I found that cloud-init pulls in netplan, so my solution was to take the static IP details in /etc/netplan/50-cloud-init.yaml and created a /etc/systemd/network/eth0.network to have all the same details in systemd format.  Then I did

pacman -R cloud-init netplan

and following that there was no more 60s delay when enabling and disabling services.

Re: [Solved] systemd daemon-reload hang - netplan bridge mul net daemons

Hello, I had the same problem. In my case, netplan was installed by cloud-init(https://cloud-init.io/) with a dependency. In fact, my arch was installed by OVH and apparently they use cloud-init to configure it. I uninstalled cloud-init and that solved my problem. yay -rns cloud-init.  thank for this post.
