Re: [HTCondor-users] Remove HTCondor worker node from a central Master

Dear John

Thank you very much for the info. I haven't tested it along with the account name (svc-jaws@xxxxxxxxxx). Just tried to use the machine name. I will try.Â

Regards,Â

Seung

The condor_off command needs to go to a condor_master daemon, so

 Âcondor_off svc-jaws@xxxxxxxxxx

orÂ

 Âcondor_off -master svc-jaws@xxxxxxxxxx

should work. The first commands turns off all of the daemons other than the condor_master. ÂThe second command turns off all daemons, including the condor_master.

If that doesn't work, Âtry

 Âcondor_off -debugÂsvc-jaws@xxxxxxxxxx

The -debug option will help to show why the condor_off command is not working.

Hi,Â

We are setting HTCondor using a glide-in way with SLURM. I was wonderingÂif there is any way I can remove the HTCondor worker processes running on a SLURM compute node. I've been testing `condor_off -name <machine_name>` and `condor_off -addr <IP:port>` but those are not successful so far.Â

For example, we have a worker node like belowÂ

```

$ condor_status -any
MyType       TargetType     Name

Collector     ÂNone        My Pool - ln010.xxx@xxxxxxxxx
Scheduler     ÂNone        svc-jaws@xxxxxxxxx
DaemonMaster    None        svc-jaws@xxxxxxxxx
Negotiator     None        svc-jaws@xxxxxxxxx
Machine      ÂJob        Âslot1@xxxxxxxxxx
DaemonMaster    None        svc-jaws@xxxxxxxxxx
Accounting     none        <none>

```

Â

And then I would like to call a command from the central toÂ

- terminate HTCondor services on n0040.yyy0

- clean up ` slot1@xxxxxxxxxx` from the Master's machine list

- terminate the SLURM job

Any help will be appreciated.

Thank you.

Best,Â

SeungÂ
