Gnus/5.13 (Gnus v5.13) Emacs/27.2 (gnu/linux)
You must have noticed that the CI is currently struggling a bit. Here is
a small recap of the situation.
* The IO operations on Berlin are mysteriously slow. Removing files from
/gnu/store/trash is taking ages. This is reported here:
We have to kill the garbage collect frequently to keep things
going. The bad side is obviously that we can't do that forever, as we
only have 9.3T and decreasing, while we aim to stay at 10T available.
* The PostgreSQL database behind ci.guix.gnu.org also became super slow
and I decided to drop it. I don't know if there's a connection with
the above point. I'm missing the appropriate tools/knowledge to
monitor the IO & file-system performances.
* The php package isn't building anymore, reported here:
https://issues.guix.gnu.org/52513. This means that we cannot
reconfigure zabbix. I removed it from the berlin configuration
* The cuirass-remote-server Avahi service is no longer visible when
running "avahi-browse -a". I strongly suspect that this is related to
the static-networking update, even if I don't have a proof for
now. This means that the remote-workers using Avahi for discovering
(hydra-guix-*) machines can no longer connect. The
ci.guix.gnu.org/workers list is thus quite empty.
* Facing those problems, I tried to rollback to a previous system
generation, but this is bringing even more issues, as for instance the
older Cuirass package, is struggling with the new database structure and
other niceties. I think out best course of action is to stick to
master and fix the above problems.
