No result coming when job submitted in lava

by Gumansingh, Smita

Hi, I am new to lava and trying to submit a job on lava scheduler ,job submitted nut no result is coming. I am trying to test the CIP Kernel on the Beaglebone Black(board is physically connected to my linux machine). Health checkup is working somehow . I am following the steps from here https://wiki.linuxfoundation.org/civilinfrastructureplatform/ciptestingrefe… Pre-requise: 1. I have built(cip_v4.4.92) the CIP Kernel with Kernel CI as the steps mentioned in https://wiki.linuxfoundation.org/civilinfrastructureplatform/cipsystembuild… 2.Target is booted and up and flashed with debian 4.9 rootfs Job Definination is pasted here https://pastebin.com/YwnPXidK Need help for going further !!!! Thanks & Regards, Smita Gumansingh

Better bootloader failure detection

by Matt Hart

Currently it is difficult to tell the difference between an infrastructure problem in a device bootloader, or a kernel failure. If a kernel silently fails to boot, LAVA throws a bootloader-commands timeout because it hasn’t matched ‘Linux version’ to know the kernel has started. However, this timeout could also be caused by a real problem in the bootloader, such as a DHCP failure or a TFTP timeout. KernelCI would like to catch actual infrastructure problems in the bootloader, but can’t tell if the kernel just didn’t boot, or the commands actually timed out in the bootloader. To fix this, we're going to: - change the bootloader-commands action to finish when it has sent the last command - have auto-login-action takeover monitoring the kernel boot process - extend bootloader-commands to match more infrastructure problems - update uboot commands to execute the commands in order (like the other bootloader implementations), rather than building a script and then calling that as the last command This work is scoped for the January 2018.1 LAVA release.

Job stuck

by Thomas Petazzoni

Hello, We have an installation where we use LAVA 2017.12. We are regularly seeing jobs that remain stuck for several days. For example, I have a job right now on the Armada XP GP that is stuck since 1 day and 11 hours. The log visible in the LAVA Web interface looks like this: http://code.bulix.org/7pvru8-255308?raw This is job #855671 in our setup. The logs on the lava-slave look like this: http://code.bulix.org/c5tejy-255312?raw So, from the lava-slave point of view, the job is finished. However, the "Job END" message had to be resent several times to the master. Interestingly, this sequence lead to a very nice: ERROR [855671] lava-run crashed On the lava-master side (which runs on another machine), the logs look like this: http://code.bulix.org/b61keb-255316?raw And this happens for lots of jobs. Pretty much every day or two, we have ten boards stuck in this situation. I have the lava-master logs with DEBUGs if this can be helpful. However, must DEBUG logs don't have the job number in them, so it makes it difficult to associate the DEBUG messages with the problematic job (since numerous other jobs are running). Does anyone has an idea what could be causing this ? Or how to debug this further ?

LXC device not working in multinode jobs

by Andrei Gheorghiu

Hi, I am having issues using an LXC device within the multinode LAVA protocole/API. The job yaml gets validated, but it fails to run with the following error: Missing protocol 'lava-lxc' in ['lava-multinode'] Full yaml used can be found here: https://pastebin.com/BUsX0G0C While searching for a fix I also found this email from a year ago, which wasn't answered (seems related): http://linaro-validation.linaro.narkive.com/mXhxhHqy/issues-with-lava-multi… Thanks, Andrei

Help: using custom script - run.sh error

by Mylene JOSSERAND

Hello everyone, I am trying to use lava with a custom script[1]. Previously, my test was used as a shell script (using exit) and I updated it to be a custom script to be able to use "skip" result. I ran a job and I got this error: /lava-854766/0/tests/1_custom-tests/run.sh: line 1: ####: not found It seems to be linked with my echo of "#### Starting NAND test ####" [2]. Here is the yaml used: https://github.com/free-electrons/test_suite/blob/master/tests/custom.yaml the source of the script: https://github.com/free-electrons/test_suite/blob/master/scripts/nand.sh the jinja file: https://github.com/free-electrons/custom_tests_tool/blob/master/src/jobs_te… and some part of the output when the test ran and failed: http://code.bulix.org/ca3mc7-254957?raw As I am new to LAVA, I have probably missed something. On the current test example [3], it seems that there is no output using "echo". Is it possible that my "echo" leads to this error? It is possible to print messages in a custom script, right?

Need Help With Simplistic Testing Over SSH

by Tan, Jian Chern

Hi, I'm trying to get started with LAVA by first attempting to do some simplistic testing over SSH to run some tests on a device that doesn't have a default template. I'm getting a few connection errors and others like output ['Permission denied (publickey,password).\r', 'lost connection', ''] and it's probably because I've misconfigured the jinja files, having little experience with these LAVA jinja templates. Attached are the job logs, jinja2 template files and the test yaml file. Could anyone point me in the right direction by either providing sample ssh jinja files and job files or pointing out the errors in my config. Thanks! Thanks! Jian Chern

Unpacking tar.bz2 root filesystems seems to malfunction

by Dragos Iorgulescu

Hi all! I am working with some Raspberry Pi boards and, while defining some particularities for booting via NFS, I came across an issue regarding the way the rootfs file is unpacked. To be more specific, after looking through the LAVA code, it seems that the untar_file() method runs on the conditional branch that states the tar members are specified. I do not understand how this implementation is designed in regards to tar archive manipulation, but the following scenario takes place: * The rootfs archive we specify in the job definition is copied and renamed, the extension being changed from .tar.bz2 to a plain .tar (which seems a bit strange tom e, on its own) * Then, after unpacking to the LAVA temp job dir, only two directories are extracted from the whole rootfs archive. I did manage to „inverveene” while the job was running and looking in the temp dir to see exactly what gets extracted. Since the rest of the folders from the rootfs are not available, the job fails once the system starts booting While investigating, I noticed that the untarf_file() method is invoked from download.py (/usr/lib/python2.7/dist-packages/lava_dispatcher/pipeline/actions/deploy/) - @ line 344 – with members being specified. I know that, because when I manually changed how this call is made and clearly specified “None” for the “member” positional argument, I get the following error at job runtime: https://paste.debian.net/1001252/ (the full job log can be found here: https://paste.debian.net/1001253/ ) The code changes I am talking about (and the code where I suspect something is ambiguous) are pointed out here: https://paste.debian.net/1001256/ . A job definition we use for this board integration can be analyzed here: https://paste.debian.net/1001257/ The full log of the initial job, that ran without my code changes, can be found here: https://paste.debian.net/1001254/ . The „kernel panic” message ocurs because, as stated in one of the errors, the “init” folder is missing, which is accurate, because only bin & dev are extracted from our rootfs tar.bz2 archive. What could we do? Is this something that needs to be adjusted/fixed in LAVA? Kind regards, Dragoș

[RFC][PATCH] lava_dispatcher/actions/boot: Add /dev/loopN device to LXC

by Aníbal Limón

From: Aníbal Limón <anibal.limon(a)linaro.org> Now the Test writer has access to the images inside the LXC to make changes previous deploy/flash into the board, in order to support mount/modify rootfs images the loop device is needed. Add a parameter in the lxc-boot action to map a free loop device (losetup -f) into the LXC.
