Hi folks,
I'm struggling to create a working multinode job and wondered if someone could help?
Here's the sample job I've submitted to try to get a handle on how multinode works:
https://validation.linaro.org/scheduler/job/1963418.1#L1745The main problem happens when LAVA executes this command on the shell:
/lava-1963419/bin/lava-test-runner /lava-1963419/1But there is no "/lava-1963419/1" directory, so then it can't find lava-common-functions and fails like this because the path is relative to a path that doesn't exist:
/lava-1963419/bin/lava-test-runner: line 18:/lava-1963419/1/../bin/lava-common-functions: No such file or directory
When I run a similar definition on a single node, it uses zero for the lava sub-dir, not 1, and it works:
That"s maybe a bug in LAVA. The number (0 or 1 or ...) allows LAVA to have many test actions in the same overlay. SO usually it should start by calling 0 and then 1, ... I will have a look.
I tried to work out what was running here, to see if I could debug the scripts to work out where the "1" comes from. I cloned the LAVA repo and I cannot see the script "environment", and the lava-test-runner sources lava-common-functions from line 16, not 18. So now I'm curious where LAVA gets its scripts from.
https://git.lavasoftware.org/lava/lava/tree/master/lava_dispatcher/lava_test... ?
Another minor point, I'm following the instructions on this link:
https://docs.lavasoftware.org/lava/writing-multinode.htmlAnd there are some dead links in there, eg.
https://docs.lavasoftware.org/lava/examples/test-jobs/first-multinode-job.ya...
https://docs.lavasoftware.org/lava/examples/test-jobs/second-multinode-job.y...
https://docs.lavasoftware.org/lava/examples/test-jobs/bbb-lxc-ssh-guest.yaml
Thanks for noticing this. In fact every files under examples/ are missing :( But not in the embedded documentation ( https://staging.validation.linaro.org/static/docs/v2/writing-multinode.html ).
Cheers
