RE: aarch64 binary convenience artifacts for Bigtop 1.2.0

[Eugene Xie <Eu...@arm.com>]

Hi, Roman,

Here comes some good news -- although a bit late. I think I've figured out why the docker daemon hang.

The reason is docker runs in 'bridge' networking mode by default which has some weird networking issue. The workaround is straight forward. I specified the docker container to run in 'host' working mode and the problem disappeared.  I managed to build 30+ components in Dev Cloud instance using the docker container.

This is how I ran the container:
docker run --net=host -v `pwd`:/ws bigtop/slaves:trunk-ubuntu-16.04-aarch64 bash -l -c 'cd /ws ; ./gradlew --continue apex-deb bigtop-groovy-deb bigtop-jsvc-deb bigtop-utils-deb crunch-deb datafu-deb flink-deb flume-deb zookeeper-deb'

Why the 'bridge' mode is failing remains unanswered/unresolved. Some of our engineer is working on that.

I suppose you can resume the work of setting up bigtop CI for AArch64 on Linaro Dev. Cloud now. Ganesh has created Dev. Cloud instances for you for that purpose. Please feel free to let us know if the workaround I provided is OK for you.

Please refer to the comments I made to Linaro bug system https://bugs.linaro.org/show_bug.cgi?id=2960 for more detailed info.


Best Regards,
Eugene

Roman,

Absolutely. I can get that done asap.
Also we would want to look at the cause itself, so we will be trying to do that as well.
And thanks for your efforts as well.

Thanks,
Ganesh

Hi!

as you saw I staged all the convenience artifacts for the release except for the aarch64. That is because the build slave is highly unstable at this point and I can't get a build at all. The symptoms range from docker daemon hanging all the time to the writes failing.

I'm starting to suspect that there's something wonky going on with the filesystem.

Now, my assumption is that this is a VM. As such a good option could be simply to recreate it from scratch and assign ample storage and CPU resources to it.

Ganesh, Jun, would something like this be possible in the next few days?

Thanks,
Roman.
