    Hi Eyal,

    removal of V1 is on the way:

    https://gerrit.ovirt.org/#/c/96031/
    https://gerrit.ovirt.org/#/c/96027/
    https://gerrit.ovirt.org/#/c/95774/

    and here's a patch that disables 'check-merged' on master:

    https://gerrit.ovirt.org/#/c/96032/

    Do we want to also disable it on 'ovirt-4.2'?


Ether, disable, or make sure it passes....

    Guys,
    The check-merged job is causing lot of noise and failures in CI
    and CQ.
    Can we drop it ASAP? and continue to discuss offline if you want
    to move that functionality to check-patch as part of V2?

    Also, if we could drop the V1 jobs that would be great so we'll
    reduce noise from failures there.

                        How much value does it add comparing to
                        check-patch?

                        If we can hold for a while with pulling the
                        plug, I can try to split it into substages in
                        stdci v2 and see if things stabilize a bit.


                    I would prefer we first work with stdci v2 in
                    order to move the functional tests there (or at
                    least play with it).
                    Then we can remove it.


                Turns out that this worth with stdci v2 - if
                check-merged fail, the change queue
                will reject the patch.

                See this mail from in...@ovirt.org
                <mailto:in...@ovirt.org> mailing list:

                    Change 95559,13 (vdsm) is probably the reason
                    behind recent system test
                    failures in the "ovirt-master" change queue and
                    needs to be fixed.

                    This change had been removed from the testing
                    queue. Artifacts build from this
                    change will not be released until it is fixed.

                    For further details about the change see:
                    https://gerrit.ovirt.org/#/c/95559/13


                According to Dafna and Barak, change queue require
                that all jobs pass, so we cannot
                have flaky job in the build.

                I hopefully removed it from stdci v2 here:
                https://gerrit.ovirt.org/c/95845/

                I don't think we should even enable check-merged
                again. All tests must run *before* we
                merge. When cannot work with a job that will randomly
                fail after merge.


            Here is another failure:

            A system test invoked by the "ovirt-master" change queue
            including change
            95817,2 (vdsm) failed. However, this change seems not to
            be the root cause for
            this failure. Change 95559,13 (vdsm) that this change
            depends on or is based
            on, was detected as the cause of the testing failures.

            This change had been removed from the testing queue.
            Artifacts built from this
            change will not be released until either change 95559,13
            (vdsm) is fixed and
            this change is updated to refer to or rebased on the
            fixed version, or this
            change is modified to no longer depend on it.

            For further details about the change see:
            https://gerrit.ovirt.org/#/c/95817/2

            For further details about the change that seems to be the
            root cause behind the
            testing failures see:
            https://gerrit.ovirt.org/#/c/95559/13

            For failed test results see:
            http://jenkins.ovirt.org/job/ovirt-master_change-queue-tester/11719/



            We are going to see more failures, since we merged
            yesterday several
            patches after the stdci v2 patch:

            8e4df87a5 storage: blocksd_test refactored to use pytest
            monkeypatching
            ede08ad53 storage: blocksd_test refactore to use pytest.xfail
            46aad2375 storage: blocksd_test convertet to pytest
            b4f2809c0 storage: Improved SD.create() docstring
            30b1423e0 virt: use log.warning(), not log.warn()
            224ebf092 ci: Added 'stdciv2' configuration file


        Hold on, since you also have V1 jobs now, patches are being
        submitted twice into the queue, and there are actually
        passing when submitted by the v1 jobs like they did before:
        
https://jenkins.ovirt.org/job/ovirt-master_change-queue-tester/11713/execution/node/85/log/

        So yeah, you should fix check-merged or disable it, but as
        long as you have the v1 jobs these failures are not causing
        any real harm, just noise.
