Two questions here: 1. If a master-only instance here, how to upgrade without data loss? 2. If a slave-only instance here, how to upgrade without data loss? Please suggest, thanks.

Loading LAVA specific kernel modules fails

by Tim Jaacks

Hello, the lava-dispatcher package installs a file in /etc/modules-load.d/lava-modules.conf, containing the following lines: install ipv6 modprobe ipv6 install brltty /bin/false On my debian 9.3 system, this file leads to failures when the systemd-modules-load service starts: Job for systemd-modules-load.service failed because the control process exited with error code. See "systemctl status systemd-modules-load.service" and "journalctl -xe" for details. The details in journalctl say: Jan 07 15:08:30 a048 systemd[1]: Starting Load Kernel Modules... -- Subject: Unit systemd-modules-load.service has begun start-up -- Defined-By: systemd -- Support: https://www.debian.org/support -- -- Unit systemd-modules-load.service has begun starting up. Jan 07 15:08:30 a048 systemd-modules-load[2088]: Failed to find module 'install ipv6 modprobe ipv6' Jan 07 15:08:30 a048 systemd-modules-load[2088]: Failed to find module 'install brltty /bin/false' Jan 07 15:08:30 a048 systemd[1]: systemd-modules-load.service: Main process exited, code=exited, status=1/FAILURE Jan 07 15:08:30 a048 systemd[1]: Failed to start Load Kernel Modules. Obviously the "install" syntax is supported only in /etc/modprobe.d: https://manpages.debian.org/stretch/kmod/modprobe.d.5.en.html But not in /etc/modules-load.d: https://manpages.debian.org/stretch/systemd/modules-load.d.5.en.html Is this a known issue?

How to run off DUT tests?

by Diego Russo

Folks, We have the need to run some tests which requires a process off DUT to be executed. Examples are: * port scan like process against the DUT * cli tests which interact with the DUT The workflow could be like: * Deploy the DUT * Boot the DUT * Run a process off DUT (actual test) * Collect test results In our setup we assume there is always a network connection between the DUT and the LAVA dispatcher. How can we achieve such workflow with LAVA? Cheers -- Diego Russo | Staff Software Engineer | Mbed Linux OS ARM Ltd.

Lavacli : configuration to get lava jobs logs

by Philippe BEGNIC

Dear all, I need to get "jobs logs" using lavacli. To do that, I use the following command : lavacli jobs logs <job_id> I can perform this operation with a user that has a profile "superuser". We have also users with restricted permissions ( they can only submit jobs using lavacli ), and I would like them to get logs using lavacli. So, I have consulted in the Lava django administration page, the users permission that can be set, but I could not find which option could allow a "basic user" to get log jobs using lavacli. Is it possible to allow a user with "basic profile" to do that ? If yes, with user permission have to be set ? Best regards Philippe Begnic

How can I run lava-publisher service in docker container?

by tomato

I am trying to submit test job using squad. When squad fetch the result of lava, the interval is too long. It takes at least 1 hour. I want to reduce fetch time as short as possible. This is what Squad team answer. Alternatively you can turn on ZMQ notifications in LAVA and run squad listener. This will cause test results to be fetched immediately after the test job finishes in LAVA. Enabling ZMQ publisher: https://master.lavasoftware.org/static/docs/v2/advanced-installation.html#c…. SQUAD listener is a separate process. It doesn't need any additional settings on top of what you already have. So I want to try restart lava-publisher service. I am running lava-server and dispatcher using Linaro lava docker image. On docker container, there is no service named lava-publisher. How can I manage this? Thanks.

Differentiate RPi3 B and B+ on LAVA

by Diego Russo

Hello, Our LAVA deployment has both RPi3 B and B+ and we are interested only on the 32bit version. The device type to use looks like: https://git.lavasoftware.org/lava/lava/blob/master/lava_scheduler_app/tests… Does this device type cover both B and B+? I mean, can we use it for B+ as well? If yes, what's the best way to differentiate those on LAVA? Creating a new device type for B+ (which is the same of the above) or using tags?

Splitting the lava-server docker image

by Olli Vainola

Hi, I've been using the lava-server docker image (hub.lavasoftware.org/lava/lava/lava-server:2018.10) for a couple of weeks and I had some problems on making the data persistent for the postgres (mapping the volume from host to container). Anyways I decided to take postgres out from the startup by modifying the entrypoint.sh file: ++++++++++++++ Added these lines after start_lava_server_gunicorn -function ++++++++++++++++++++++++++ if [[ ! -z $DJANGO_POSTGRES_SERVER ]]; then txt="s/LAVA_DB_SERVER=\"localhost\"/LAVA_DB_SERVER=\"$DJANGO_POSTGRES_SERVER\"/g" sed -i $txt /etc/lava-server/instance.conf fi if [[ ! -z $DJANGO_POSTGRES_PORT ]]; then txt="s/LAVA_DB_PORT=\"5432\"/LAVA_DB_PORT=\"$DJANGO_POSTGRES_PORT\"/g" sed -i $txt /etc/lava-server/instance.conf fi ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ---------------------------- Commented out these lines ----------------------------- # Start all services #echo "Starting postgresql" #/etc/init.d/postgresql start #echo "done" #echo #echo "Waiting for postgresql" #wait_postgresql #echo "[done]" #echo -------------------------------------------- ---------------------------------------------------- After that I created a new Dockerfile and built a new image: +++++++++++++++++++++++++ Dockerfile +++++++++++++++++++++++ FROM hub.lavasoftware.org/lava/lava/lava-server:2018.10 COPY ./entrypoint.sh /root/ RUN chmod 755 /root/entrypoint.sh ENTRYPOINT ["/root/entrypoint.sh"] ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ >> sudo docker build -t lava-server:mod . Just to get all up and running I made a docker-compose.yml file to kick postgres and lava-server up +++++++++++++++++++++++++++ docker-compose.yml +++++++++++++++++++++++++ version: '3' services: postgres: image: postgres:11 restart: always environment: POSTGRES_DB: lavaserver POSTGRES_USER: lavaserver POSTGRES_PASSWORD: d3e5d13fa15f lava-server: depends_on: - postgres image: lava-server:mod environment: DJANGO_POSTGRES_PORT: 5432 DJANGO_POSTGRES_SERVER: postgres ports: - "80:80" +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I still feel that there is too much going on inside that lava-server:mod image, since it has following softwares running: * Lavamaster * Gunicorn * Logger * Publisher What do you think, should I still break it into smaller pieces? Pros on this would be that softwares wouldn't die silently (started by using '&' and docker could try to restart them), logs would be in their own logs windows' (docker log CONTAINER) and containers themselves would be more configurable via environment variables.

Change archive and media path

by Axel Lebourhis

Hi everyone, I want to change the default path of MEDIA_ROOT and ARCHIVE_ROOT. So in /etc/lava-server-settings.conf I wrote this : "MEDIA_ROOT": "/data/lava/var/lib/lava-server/default/media", "ARCHIVE_ROOT": "/data/lava/var/lib/lava-server/default/archive", This seems to work but the web UI doesn't display the job output and when I try to download the plain log, it returns an error saying it can't be found. Could you tell me what should I do to make the web ui find the job outputs ? Best regards, Axel
