service enable/disable not working on fresh systemd debian install

Hi all,

I’m trying to use ansible to handle services on a fresh Debian Wheezy on which I installed and enabled systemd (by following these instructions).

Using the service module, start/stop seems to be working ok, example below :

$ ansible […] -m service -a “name=acpid state=stopped”
success >> {
“changed”: true,
“name”: “acpid”,
“state”: “stopped”
}

then :

systemctl status acpid.service

acpid.service - ACPI event daemon
Loaded: loaded (/lib/systemd/system/acpid.service; enabled)
Active: inactive (dead) since Tue, 10 Sep 2013 11:31:41 +0200; 4min 19s ago

But when it comes to service enabling/disabling, it does not seem to be working although ansible says the change was successful:

$ ansible […] -m service -a “name=acpid enabled=false”
success >> {
“changed”: true,
“enabled”: false,
“name”: “acpid”
}

still, the service stays enabled in systemd:

systemctl is-enabled acpid.service

enabled

Maybe it’s because ansible first tries to use another tool like update-rc.d instead of systemctl ?
Or is there something wrong with my setup… ?

Thanks

What version of Ansible are you using?

I’m using the last version from git checkout :
ansible 1.3 (devel 808d9596b2) last updated 2013/09/10 10:27:35 (GMT +200)

tried also with the last version available from EPEL on CentOS (ansible 1.2.3) but the result is the same.

Ok when you say checking from EPEL I think you mean the version from ansible, not acpid?

We’ll look into it.

Yes I was talking about installing ansible from EPEL.

I did some more tests.
I tried creating a dummy systemd unit in /etc/systemd/system/testd.service.
This time, using Ansible to enable/disable the service worked perfectly.

Next step, I created also a dummy old-fashion init script in /etc/init.d/testd,
and added a symlink in /etc/rc5.d… after that I could not use Ansible anymore to enable/disable the service.

So I guess this confirms my first guess…

(I did these last tests with the latest ansible from git)

The underlying issue here is that when Ansible sees the update-rc.d binary, it assumes the services will be managed either through upstart or sysV. I’ve created a patch to add in a check for systemctl-managed services, so that it will use the proper binary to manage the service:

If you could give this some testing and confirm it fixes your issues, I will get it merged in to the development branch today.

Thanks!

Hi James,

I have just applied the patch, tried to disable/enable several systemd-managed services using the service module and now it’s working.
That was fast, thanks a lot !

Excellent, I had already done a bit more testing too and went ahead and merged this in, so it will be included in 1.3.

Thanks for catching this and reporting it!
