Hello,
We've identified that powerkvm CI seems to be in a loop attempting to clone nova. It would be helpful if we could get this to stop :)
It's just a guess, but we found a similar problem in OpenDev where the executors were attempting to cache the repo, but their default timeout of 300 seconds wasn't long enough to complete the clone. They would kill their clone attempt and start over again immediately. In the Zuul executor logs you'll see something like
2020-12-10 02:02:08,578 ERROR zuul.ExecutorServer: [e: ...] [build:...] Got exception while updating repo gerrit/openstack/nova
with a full traceback above.
Our solution was to increase the git_timeout [1] to long enough for the clone to complete. The recent upgrade may be to blame. We're experimenting with different options for gc/repack, but cloning the repo from gerrit directly it close to 2gb. Another option is to convert this to cloning to https://opendev.org.
Please reach out if there is anything we can do to help.
Thanks,
-i
