Re: [HTCondor-users] A condor_off -peaceful stops all startd_cron jobs

Hi, Michael.

Off the top of my head I can think of two things two try as a work-around

1. Use condor_drain -exit instead of condor_off -peaceful
2. Use a continuous STARTD_CRON job (MODE = WaitForExit)

I'm not sure either of these would work though. I'll have to do some testing and get back to you.

Hooks — HTCondor Manual 9.4.0 documentation

Subject: [HTCondor-users] A condor_off -peaceful stops all startd_cron jobs
