Recently I noticed that I'm not getting substitutes for Mutt.

Looking at the ci.guix.gnu.org web interface, it seems that we stopped
building Mutt about a month ago:

https://ci.guix.gnu.org/search?query=spec%3Amaster+mutt-2.0.7+system%3Ax86_64-linux

And `guix weather` confirms that we seem to have stopped building it:

I wonder what is going on?

Hello Leo,

> I wonder what is going on?

The current mutt package output is:

--8<---------------cut here---------------start------------->8---
mathieu <at> meije ~$ guix build mutt  --no-grafts
/gnu/store/c0wp5iq5k11mvqrm4bs011qlm7qy48ia-mutt-2.0.7
--8<---------------cut here---------------end--------------->8---

The last mutt build on the master specification is
https://ci.guix.gnu.org/build/321231/details, that reports the same
output. This build has not been attempted again because its output
didn't change.

The substitute is however missing as you noticed. That's because the
Cuirass GC root expired, and the nar file also probably expired its 90
days TTL.

We should maybe increase this TTL, or make sure that every "latest"
master derivation is covered by a GC root.

WDYT?

Thanks,

Mathieu

Mathieu, do you have Zabbix graphs showing how we’re doing wrt. storage
on berlin?

If we’re doing well, we should definitely increase the ‘guix publish’ TTL.

Thanks,
Ludo’.

Here's one attached, we have been stable around ~10TiB of free space for
the last couple of months.

What about increasing it to say 180 days?

Thanks,

Mathieu

Interesting.

The graph suggests that GC is running everyday to collect probably a few
GiBs.  Perhaps we should ‘guix gc -F15T’ once a week to reduce GC work
on subsequent days?

Sounds good to me.  Can you make the change?

Thanks,

That was done with ca6f40272fdf5644597f6ad2e38fa8ab2907d126.

Closing,
