Description

condor_off shuts down a set of the Condor daemons running on a set of one or more machines. It does this cleanly so that checkpointable jobs may gracefully exit with minimal loss of work.

The command condor_off without any arguments will shut down all daemons except condor_master . The condor_master can then handle both local and remote requests to restart the other Condor daemons if need be. To restart Condor running on a machine, see the condor_on command.

With the -subsystem master option, condor_off will shut down all daemons including the condor_master . Specification using the -subsystem option will shut down only the specified daemon.

For security purposes (authentication and authorization), this command requires an administrator's level of access. See section on page for further explanation.

<a.b.c.d:port>

Send the command to a machine located at <a.b.c.d:port>

-all

-subsystem master startd schedd collector negotiator kbdd quill

Send the command to the named daemon. Without this option, the command is sent to the condor_master daemon.

Exit Status

condor_off will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.

Examples

To shut down all daemons (other than condor_master ) on the local host:

% condor_off

To shut down only the condor_collector on three named machines:

% condor_off cinnamon cloves vanilla -subsystem collector

To shut down daemons within a pool of machines other than the local pool, use the -pool option. The argument is the name of the central manager for the pool. Note that one or more machines within the pool must be specified as the targets for the command. This command shuts down all daemons except the condor_master on the single machine named cae17 within the pool of machines that has condor.cae.wisc.edu as its central manager:

% condor_off -pool condor.cae.wisc.edu -name cae17
