"No such method: u'results.run_query'" when trying to access queries from a Python script

by Dragos Iorgulescu

Good morning everyone! I am trying to "play around" with user queries in LAVA2. After reading about them (https://validation.linaro.org/static/docs/v2/lava-queries-charts.html?highl… ), I downloaded the provided sample script (https://validation.linaro.org/static/docs/v2/examples/source/query-results.… ), made the required updates (user names, query name, hostname & the such) and gave it a try. The only thing I get stuck on is an XML-RPC lib error: "No such method: u'results.run_query'" (the whole traceback can be seen here: https://paste.debian.net/993833/ ) I have attached the modified script I am trying to run at the moment and a screenshot of the query settings. The API Help page is not reachable/present at the moment (nor on https://validation.linaro.org/static/api/help or on our own LAVA instance ), so I am unable to check whether or not the method's name has changed since the last doc update. What am I missing or doing wrong? Many thanks in advance! Have a great day! -- /Dragoş

PXE Booting and flashing device

by Rees, Kevron

I have a minnowboard turbot device that I want lava to boot, flash, reboot to flashed image, and then run tests. I would like to boot the device via PXE networking to an initramfs where I will flash an image to permanent storage. I can use efibootmgr within the initramfs image to set next-boot to the permanent storage device. Once booted from the permanent storage device, lava tests will run as per normal. It appears that many of the ipxe examples I have found simply run tests on the initramfs itself. Is it possible to flash the device once the initramfs has booted? It seems like it would be simple for lava-dispatcher to run wget http://someurl/foo.img | dd of=/dev/sda once the initramfs has reached login. However, I do not know if there is such a deploy mechanism. Does anything already exist within lava to help achieve this model? Is there a better way? Any feedback would be appreciated. -Kevron

Truncated commands & output in LAVA2

by Dragos Iorgulescu

Hi all! We have been working on integrating a cn8304-based board (uses uboot). We noticed some strange behavior that might be related to LAVA2. On average, 2 out of 3 job runs end up with errors/timeouts. We use the same job definition and device each and every time. Looking through LAVA logs, it seems that commands and some output gets truncated, thus malforming the commands being sent or the prompts that LAVA expects. The prompt we expect is "EBB8304> ", but sometimes it gets truncated to "304>". Also, a command gets mixed up somehow, and instead of "setenv loadinitrd 'tftpboot 0x60000000 358/tftp-deploy-VLCRzw/ramdisk/ramdisk.ext4.gz.uboot'", the board receives "EBB8304> setenv loadkernel 'tftpboot 0x40setenv loadinitrd 'tftpboot 0x60000000 358/tftp-deploy-VLCRzw/ramdisk/ramdisk.ext4.gz.uboot'" Details: * The job definition: https://paste.debian.net/993349/ * An excerpt from the LAVA2 job log/output, showing what gets mixed up: https://paste.debian.net/993350/ * The plain job log is attached to this e-mail Many thanks in advance! -- /Dragoş

LAB Notice: Planned maintenance

by Dave Pigott

Hi all, Starting this week, we are finalising the transition of LAVA main production to LAVA V2. The main update and hopefully minor downtime, will commence at 09:00 UTC on Monday 6th November. Along with this we will also be upgrading all micro-instances to Debian Stretch and LAVA 2017.11. There will be a brief period on Monday morning, which should be less than an hour, when remote logins will be disabled as we upgrade the gateway server. Please note, that when validation.linaro.org comes back online, LAVA V1 job submissions will be rejected, so if you have any bots which auto-submit V1 jobs, please work with us to transition them to V2. Thanks Dave ---------------- Dave Pigott LAVA Lab Lead Linaro Ltd t: (+44) (0) 1223 400063

LAVA Error 503 Service Unavailable Error

by Tan, Jian Chern

Hey does anyone know why i'm getting an Error 503 Service Unavailable after installing LAVA on a new server? I have it installed on another system and i've never gotten this error on that system before. If it helps, i'm working behind a corporate proxy and here are the pertinent lines from lava-server.log in the apache log folder. [Fri Oct 06 20:01:57.729804 2017] [proxy:error] [pid 2887:tid 140627852187392] (111)Connection refused: AH00957: HTTP: attempt to connect to 127.0.0.1:8000 (127.0.0.1) failed [Fri Oct 06 20:01:57.729851 2017] [proxy_http:error] [pid 2887:tid 140627852187392] [client *IP*:56521] AH01114: HTTP: failed to make connection to backend: 127.0.0.1 Thanks!

lava-tool auth-add problem

by Michael Chen

Hi lava users, We're trying to use lava-tool to automate the job submit process, but having problem on using "lava-tool auth-add" command. The error message is ERROR: Username provided but no token found. I tried the instructions from the following page, but without luck. https://validation.linaro.org/static/docs/v2/lava-tool-issues.html I am pretty sure the user name, token, server url are correct since we tested it with the example python script from above page's second paragraph, and we can submit job through it. The version of lava-tool is 0.23-1 and lava-server is 2017.10-1+jessie. Does anyone have similar issue? Thank you. Michael Chen

Test job failed due to uefi-menu-selector timeout

by Arthur She

Hi, I got a problem in LAVA v2. My test jobs failed due to uefi-menu-selector timeout occasionally. Like this one <https://staging.validation.linaro.org/scheduler/job/188583> and this one <https://staging.validation.linaro.org/scheduler/job/185376>. When it happened, I usually re-submit the test job and, sometimes, it got recovery and had the test job run successfully, like this <https://staging.validation.linaro.org/scheduler/job/185377>. However, we're working on our own CI loop now, the test job <https://staging.validation.linaro.org/scheduler/job/194340> is submitted automatically. It doesn't make sense to re-submit the test job. Any ideas? Thanks, Arthur

I met several problems. Some of them were a matter of overriding variables. For example, I cannot use dhcp for the board so I had to change uboot_ipaddr_cmd and base_ip_args. There was one variable (SERVER_IP) I couldn't override, so I had to modify base-uboot.jinja2 for it. my jinja2: {% set uboot_serverip = '192.168.1.66' %} base-uboot.jinja2 # vi /etc/lava-server/dispatcher-config/device-types/base-uboot.jinja2 {% set base_uboot_tftp_bootcmd = uboot_tftp_bootcmd|default( " - setenv bootcmd '" + uboot_ipaddr_cmd|default('dhcp') + "; setenv serverip " + uboot_serverip|default('{SERVER_IP}') + "; run loadkernel; run loadinitrd; " + run_load_fdt + uboot_bootx_cmd|default('{BOOTX}') + "' - run bootcmd") -%} Note: I tried modifying LAVA_SERVER_IP and LAVA_NETWORK_IFACE in /etc/lava-dispatcher/lava-dispatcher.conf as well but it didn't work. Those settings are only relevant for V1, so V2 tests will ignore these. Setting the SERVER_IP in the device configuration is the wrong approach. This IP address is for the dispatcher, so it needs to be added to the dispatcher configuration. In V2, the dispatcher configuration is sent from the master. Setting a fixed IP address for the dispatcher is already supported. See /usr/share/lava-dispatcher/dispatcher.yaml for an example. See https://validation.linaro.org/static/docs/v2/pipeline-admin.html#extra-disp… You need a file named according to the hostname of the dispatcher as it appears in the dispatcher-master log file. If you consider it useful, please consider including it in the mainstream code.
