Re: [HTCondor-users] Removing a node ungracefully from the master.

[Matt Wallington <matt@xxxxxxxxxxx>]

So if I understand correctly, that's to prevent additional jobs from running on that machine correct?  But how do I have Condor immediately stop and resubmit the jobs that were running on that machine to the next available machine?  I essentially want that machine to go away from condor until it becomes available again and any jobs that were running on it to go back into the queue to be matched on another machine.

Is this possible?

The condor_advertise man page covers this pretty well.
