As of Fri Nov 12 03:23:10 PM EST 2021 the s390x builder appears to be missing in action -- can't see any recent builds (24 hours) on https://farmer.golang.org/ for it, and I am unable to create a gomote.

Per owners, pinging

@ruixin-bao

Thanks.

Weird, I don't see an entry for it on https://farmer.golang.org/ at all (not even to indicate that it is missing)...

That's because the builder's ExpectNum is 0.

@ruixin-bao Once the builder is back, should we set ExpectNum to 1, or are there more builders of this type that normally connect?

@dmitshur, There are two hosts: go01.novalocal 148.100.113.12 and go02.novalocal 148.100.113.47.

I had a look and it was failing because /data/golang/workdir did not exist on either host. I don't know why it was missing. I created the directory and builds are running on both hosts again.

I'll watch and see how the builds go. If there is anything else I should check, please let me know.

Hi,

Sorry for the late reply, and thanks @jonathan-albrecht-ibm for looking into it. I am on vacation till November 17. If this issue still exists, let me or Jon know, I will help look more into it when I am back. Thanks.

Thank you @jonathan-albrecht-ibm and @ruixin-bao.

The builders are back, so I'll mark this as resolved.

I've also sent CL 363984 to set ExpectNum to 2, and added builder owners based on conversation in https://groups.google.com/g/golang-dev/c/obUDaYbaxXw/m/R2JTockmAAAJ. Thanks.

Also set ExpectNum 2, since there are 2 known reverse builders.

Updates golang/go#49557.
