Hi Egor,
    Do we need to add a cinder volume to the master nodes for Kubernetes as
well?  We did not run Docker on the master node before so the volume was
not needed.
Ton Ngo,

Hi Egor,

Thanks for investigating on the issue. I will review the patch. Agreed. We
can definitely enable the swarm tests if everything works fine.

Best regards,
Hongbin

Hongbin,

I did some digging and found that docker storage driver wasn’t configured
correctly at agent nodes.
Also it looks like Atomic folks recommend use deicated volumes for
DeviceMapper (
http://www.projectatomic.io/blog/2015/06/notes-on-fedora-centos-and-docker-storage-drivers/
).
So added Cinder volume for the master as well (I tried create volumes at
local storage, but it’s not even enough space for 1G volume).

Please take a look at https://review.openstack.org/#/c/267996, did around
~12 gates run and got only 2 failures (tests cannot connect to master, but
all containers logs looks alrignt. e.g.
http://logs.openstack.org/96/267996/3/check/gate-functional-dsvm-magnum-swarm/d8d855b/console.html#_2016-01-18_04_31_17_312
), we have similar error rates with Kub. So after merging this code we can
try to enable voting for Swarm tests, thoughts?

There are other symptoms as well, which I have no idea without a deep dip.

Hongbin,

I belive most failures are related to containers tests. Maybe we should
comment only them out and keep Swarm cluster provisioning.
Thoughts?

Hongbin,

I’m not aware of any viable options besides using a nonvoting gate job. Are
there other alternatives to consider? If not, let’s proceed with that
approach.

Clark,

That is true. The check pipeline must pass in order to enter the gate
pipeline. Here is the problem we are facing. A patch that was able to pass
the check pipeline is blocked in gate pipeline, due to the instability of
the test. The removal of unstable test from gate pipeline aims to unblock
the patches that already passed the check.

An alternative is to remove the unstable test from check pipeline as well
or mark it as non-voting test. If that is what the team prefers, I will
adjust the review accordingly.

Best regards,
Honbgin

Hi folks,

It looks the swarm func test is currently unstable, which negatively
impacts the patch submission workflow. I proposed to remove it from Jenkins
gate (but keep it in Jenkins check), until it becomes stable.
Please find the details in the review
(https://review.openstack.org/#/c/264998/) and let me know if you have any
concern.

Removing it from gate but not from check doesn't necessarily help much
because you can only enter the gate pipeline once the change has a +1 from
Jenkins. Jenkins applies the +1 after check tests pass.
