Hi,

I have an issue with my Guix configuration. From a certain update my
system fails to boot. It successfully boots into kernel and starts
shepherd. But after that shepherd fails to activate some necessary
service and the system is softlocked.

The problem is that I can't neither control the system in the booted
state at that point nor I can check the logs, as logd wasn't started
yet, so kernel messages are only preserved in memory and on the screen.

But I cannot scroll the screen, and can't interact with the system in
any way. I can at least display some of them with disabling silent
kernel, but the issue is the root cause is scrolled away too fast to be
read.

My question is, is there a way to debug this? I mostly need help with
identifying the failing service, once I have it, I think I can sort it
out.

Best regards,
Maya

I have had the same problem repeatedly one one piece of equipment.  It
is vexing to the n-th degree.

I disable all suspect services and then add them back with an ad-hoc
geometric algorithm: I add half and, if those works, add a quarter, and
then an eighth...

There is some disagreement one how the Shepherd can produce better
logging output.  Some information may be in /var/log/messages but it can
be hard to find.

You are not alone.  Please post a reproducer if you have one.

Kind regards
Felix

Last month, Shepherd integration in Guix was fixed so that failure to
load one service would not prevent the system from loading and starting
other services:

  https://issues.guix.gnu.org/71144

Does the problem still manifest on a system reconfigured from a commit
after cca25a67693bb68a1884a081b415a43fad1e8641?

(See also <https://issues.guix.gnu.org/71193> for a recent example in
that vein and how the change above addresses it.)

HTH,
Ludo’.

It did not fix the issue, but I had noticed that one of the services
that was failing was fuse, as it was the last service listed as failed
and the file-systems service depended on it.

Disabling fuse fixed the issue. I still don't know how to fix the issue
properly, but at least I can reconfigure my system now <3

I have a reproducer!  In the code below, please change "sunday" to "0",
together with this line in your "services":

     (service mdadm-resync-service-type)

When reconfiguring, you should see something like:

    guix deploy: warning: an error occurred while upgrading services on
    'YOUR-FQDN': %exception #<inferior-object #<&action-exception-error
    service: root action: eval key: %exception args: ("#<&message
    message: \"calendar-event: 0: invalid day of week\">")>>

That system should refuse to boot.  Interestingly, the Shepherd will
block in such a way that even the Magic SysRq key 'i' which is normally
enough will not stop it.  I have to go all the way *backwards* to 'b' in
the sequence B-U-S-I-E-R. [1]

Ludo', thank you for making the #:days-of the week symbolic [2] and also
for fixing the Shepherd to be able to show status and reboot again! [3]

Kind regards
Felix

Sorry, I meant to write 'e' which presumably refers to SIGTERM rather
than SIGKILL.

(un?)fortunately, i can't reproduce it on a recent guix and shepherd.

both the devel branch and my branch (which includes extended error handling) works as expected. they simply skip registering this service and log the error:

Jul  2 14:59:05 localhost vmunix: [    2.936007] shepherd[1]: Exception caught while loading '/gnu/store/h6c15frnkx7arkm2bna20js3v90880bh-shepherd-mdadm-resync.go': #<&message message: "calendar-event: 0: invalid day of week">

i forgot to add that it's fixed by a guix commit:

services: shepherd: Failure to load a service does not prevent booting.

Hi Attila,

Okay, then there is still another problem.  I am unable to reconfigure
my systems via 'guix deploy' when a timer is enabled already.  I am
trying to add a second timer.

The command stalls with messages like this:

    The following derivations will be built:
      /gnu/store/11nlp3k2lq25ijb4m9x0mj7phprjx9f6-remote-exp.scm.drv

    guix deploy: sending 2 store items (0 MiB) to 'wallace-server.us-core.com'...

The issue occurred for the two timers below, but I believe the issue is
unrelated to the type of timer or their order.

Attached is a low-res image of the console output.  I was unable to
capture the error in any other way.  Sorry to spam the list with 7kB.

Kind regards
Felix

In ice-9/boot-9.scm:
  1676:22  0 (raise-exception _ #:continuable? _)
--8<---------------cut here---------------end--------------->8---

Note that this is asking for a Sunday 1st, or 2nd, etc. until 7th,
contrary to what the comment says.

It should be able to find Sunday, Sept. 1st at least.

I’ll investigate but in the meantime maybe what you want is to remove
#:days-of-month?

Maybe some confusion between symbolic and integer days-of-week?

I'm not sure about that.  To me, the timers seem to run at the
intersection of all values (effectively, a logical AND).  I'd like to
pick any Sunday that occurs during the first seven days of any month.

It would be the first Sunday in each month.

Also, here are some brief code questions, if you would be so kind to
entertain them:

Why are the ranges for minutes here [1] 0..60 instead of 0..59, and 0..7
for days-of-week instead of 0..6, please? Even if the intervals were to
exclude an end point [2] they seem inconsistent with 1..12 for the
months or 1..31 for days-of-month.  Also, should the interval for the
hours be 0..23 instead of 0..60?

Thank you for your hard work on these great new features!

Kind regards
Felix

Oh right.  Now fixed!

This code describes a count and a minimum value, rather than an actual
range: 60 minutes and starting from 0, 12 months and starting from 1,
etc.

Thanks for your feedback!

Thanks for that!  Shepherd timers are a cool thing for Guix.  They are
ready to be merged.

I also hope to look into the syslog and log-rotation features today, but
please don't wait if you are comfortable with them.

Kind regards
Felix

sadly, i cannot test your reproducer without substantial work.

my patches that clean up error handling in shepherd are from before Ludo added timers; i.e. it's once again bitrotten.

contributing to guix feels like an uphill battle. i stopped rebasing my shepherd commits. abandoning them does feel like an enormous waste, but i'm cutting my losses at this point.

You were probably right to do so.

From what I remember, Ludo' did not like debugging statements all over
the place.  There was a disconnect that prevented a productive
cooperation between Ludo' and you.

Also, Ludo' is probably getting ready to cut 1.0 at this point and turn
the Shepherd over to someone for Goblins and actor enhancements.  The
code base may depart even further.

It may not have been a waste, however.  One day your understanding of
the Shepherd's internals may help you to offer features the maintainer
is excited about!

Kind regards
Felix
