”502 Proxy Error” for large job log & details (in the WEB UI)

by Dragos Iorgulescu

Hello again! After managing to run a consistent series of tests on one of our boards, I came across a situation where the job log seems to be too big for LAVA to display. When clicking the ”Job details” button, the server eventually sends a ”502 Proxy Error” message. Is there a setting or a workaround to make LAVA serve the job log & details in ”chunks”? I did download the plain log (using, for example, http://LAVA_HOST/scheduler/job/JOB_ID/log_file/plain), and it is, indeed, huge (29 MB), but I was just curious if, maybe a ”log rotation”-like mechanism could be used in these situations (somehow). Thanks in advance! -- /Dragoş

Git error after upgrading to 2017.10-1: "fatal: index-pack failed"

by Dragos Iorgulescu

Hi! Just upgraded from 2017.6 to 2017.10-1. Tried re-running some jobs that worked fine just before the upgrade and noticed that git checkouts can no longer pe performed. The encountered error is: fatal: The remote end hung up unexpectedly\nfatal: early EOF\nfatal: index-pack failed\n Tried checking out manualy on the host, using the same repo. It works. How could I proceed investigating this? Could this be related to some lava user configuration that got reset (I don't know if git-related configs are associated with LAVA)? Thanks in advance (again)! P.S: I have attached the plain job log -- /Dragoş

LAB Notice: Planned maintenance

by Dave Pigott

[bcc’d to everyone to ensure we get full coverage. Please ignore if you have no interest in LAVA and the Lab] 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 <http://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. For future reference, for announcements about Lab availability, you should join the lava-users mailing list. Thanks Dave ---------------- Dave Pigott LAVA Lab Lead Linaro Ltd t: (+44) (0) 1223 400063

Very long output line seems to interfere with board output/job run

by Dragos Iorgulescu

Good morning everyone! While running some tests using our Linux distro and a SuperMicro Intel D1521 board, we encounter a situation where a very long line (shown as a "broken line" in LAVA's logs - in the WEB UI) seems to interfere with the job run, in a sense that the job eventually ends in a timeout. This does not happen when that particular set of tests is not run and I am wondering if this might be a LAVA issue. -------------------- A bit of context, first. SuperMicro boards "make sure" your board connection options are limited to using SoL (serial-over-lan), IPMI and a serial port (but in a very limited manner). One is not able to do a "typical" image load, since you may not specify hardware addresses or properly interact with the bootloader. This led to an approach which is best illustrated in the attached diagram. For short: LAVA instantiates an LXC container, from where we run a series of scripts to prepare the board (copy some images & files on an already available Linux instance, altering the Grub menu and then rebooting the board, making it start the image we wish to test) and then run remote commands via SSH. So, basically, the LXC container runs each and every command on the board, acting as the middleman. ------------------- Now, we have the following: * https://paste.debian.net/993516/ -> plain log excerpt that contains the very long line I was talking about (please see line no. 90) * https://paste.debian.net/993517/ -> job definition * https://paste.debian.net/993518/ -> test definition Is there a way to further investigate if this type of output is "giving LAVA a hard time"? Is there a setting that limits interpreted output, somehow? May it be that this is a LAVA issue? Kind regards! -- /Dragoş

"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
