Re: [HTCondor-users] peaceful node drain and shutdown

["Fox, Kevin M" <Kevin.Fox@xxxxxxxx>]

I'm guessing the condor_drain command will have similar issues to the condor_off -peaceful command? That you have to have all the permissions setup right?

The nice thing about the START=FALSE config trick is you only need root on the machine to do it.

Thanks,
Kevin

Hi Kevin,

If the above satisfies your needs, great.  But just wanted to point out
you can do the same thing (drain a node gracefully) with the
condor_drain tool.  Do "man condor_drain", or see
  http://htcondor.org/manual/v8.4/condor_drain.html

Also in the upcoming HTCondor v8.5.6, the condor_drain functionality is
exposed via HTCondor's Python API. :)

regards,
Todd
