Re: [Condor-users] deny jobs, but letting the que run.

I usually replace the worker node configuration files (they are all soft-links anyway) with one that has 
  START = FALSE
  REQUIREMENTS = FALSE
and then issue condor_reconfig. No new jobs ever start but queues remain happy. This doesn't stop any new submissions coming in however, so the queues may build up while you wait for the system to drain.

How about turning off the negotiator daemon?  Any jobs not yet matched
should be stuck in the queue, while running jobs will be unaffected
unless they are otherwise vacated.

Yes that is what I ended up doing. I took it down, and sent an email to
the users who had jobs running about when they could restart them. I
know that is far from optimal.

    [more thoughts]

    Might it be possible to "hack" it, but doing a condor_config_val
    of the HOSTALLOW values for the schedd to prevent changes being made
    to it
    (or would that make a right mess?).

    Another thought is that if you have some jobs that could yet take 6
    months,
    you probably don't want to shutdown the queue to further updates yet
    allow
    this job to finish. You just want to shutdown now and then bring things
    back to life when the machine comes back

        I mentioned exactly this scenario to the dev team in June. Their
        response:


        "There are tricks you can play, like replacing condor_submit
        with a script that denies use of it, but if users found the old
        script, or did a remote submit, it wouldn't stop them.

        I'm going to record your sugesstion into our feature tracking
        system because it is a really good idea. So maybe it'll show up
        in a later revision of Condor."



        I do not know if they have already implemented something in a
        newer version that allows this, but I don't believe so.

            Hello Condor user.


            I am administering a smallish condor cluster here and I am
            upgrading it from 6.8.5 to 6.8.7 Everything seems fine so
            far. I need to create a service window where I can start up
            the new version. One of the users currently have  a few
            hundred jobs in que. I want to let all of these jobs run,
            but deny any more jobs started until I can finish the
            upgrade? Is there a easy way to fix this? All of the
            computers are now allowed to submit jobs. I would be happy
            to not have to go onto each explicit deny logon. Is there
            something I can do to the master? I'm sure this is covered
            somewhere in the manual just that I can not see it.


            I am pretty new to condor so please bear with me :)


            Best Regards

            Bjørn Dyresen.
