Running MultiNode job on specific devices

by Frank, Matthias

Hello lava users, how can I run a multinode job on specific devices instead of (a possible set) of device_types? I plan to run CAN or RS485 communication tests which requires a wired connection between duts. Is is possible to submit a job to theses special duts or should is have device_types with only on device instance? Greetings, Matthias

jobs using notify with tokens, resubmit as different user

by Kevin Hilman

How can you have more than one LAVA user have the same token secret (e.g. for a notify callback.)? Example use case: - LAVA job with notify callbacks using token names - submited as user "bob", token names of "bob" map to actual token secrets - job fails - user "lab-admin" fixes some lab issues, re-submits job - job passes, but callbacks fail because tokens are associated with user "bob" Since the re-submitted job runs as user "lab-admin", the same token names and corresponding secrets don't exist. Naively, user "lab-admin" tries to copy the token secrets from user "bob" keeping the same token names, but this fails saying that "secret already exists". Why can't different users have the same secrets? I haven't looked at the code, but this limitation kind of suggests that the secret itself is the key in the db, which would prevent multiple secrets of the same. Kevin

Build information in metadata

by Frank, Matthias

Hello lava users, I use in a test job linuximage, rootfs and dtb from file server location retrieved via http. These files are nightly build from Jenkins. The file links are static so I can use new images within the same test job definition. Jenkins generates also a build information text file with commit IDs an so on. How can I integrate the content of this file in the job metadata or job result log? Using metadata: build-readme: <link> in the job definition is not possible because the link is stable over different build, but the file content is changing. The DUT has no access to the file location because it is in an isolated network. Is there a way to cat the file content on the worker to metadata or job result? Greetings, Matthias

Invalid device configuration

by Frank, Matthias

Hello lava users, my lava 2019.01 shows me a device with Health == Bad. The Transitions log give that message: March11, 3:02p.m. lava-health Good → Bad (Invalid device configuration) Where can I found information about a misconfigured device? The log files did not provide (in my eyes) sufficient information. As Health checks I use the smoke-tests. Kinds Regards, Matthias

apt get install hang

by cnspring2002

I use lxc-mocker in docker container, everything is ok. Just if the package did not install in advance, then next command will hang in web: lxc-create -t ubuntu -n test_lava -- --release xenial --mirror http://mirror.bytemark.co.uk/debian --packages systemd,systemd-sysv --arch amd64 I enter the container, see: root@df67cf292479:/# ps -ef UID PID PPID C STIME TTY TIME CMD root 1 0 0 17:20 pts/0 00:00:00 /usr/bin/python3 /usr/bin/lava-slave --level DEBUG --log-file - --master tcp://192.168.1.10:5556 --socket-a root 8 0 0 17:20 pts/1 00:00:00 /bin/bash root 13 1 0 17:20 pts/0 00:00:00 lava-run [job: 837] root 19 13 0 17:20 pts/0 00:00:00 /bin/bash /usr/bin/lxc-create -q -t ubuntu -n test_lava -- --release xenial --mirror http://mirror.bytemark.c root 261 19 1 17:20 pts/0 00:00:00 apt-get -q install -y systemd systemd-sysv root 473 8 0 17:21 pts/1 00:00:00 ps -ef Seems "apt-get install" hang, but if I pre-install the systemd,etc, then everything will ok, the lxc-create will not hang. The same for lxc-attach mocker etc, all will hang if do "apt-get install" & no pakcage preinstall. Please suggest, thanks.
