By default, it does this cleanly, so that jobs have time to shut down. The command *condor\_off* without any arguments will shut down all daemons except *condor\_master*, unless **-annex** *name* is specified. The *condor\_master* can then handle both local and remote requests to restart the other HTCondor daemons if need be. To restart HTCondor running on a machine, see the *condor\_on* command. When the **-drain** option is chosen, draining options can be specified by using the optional **-reason**, **-request-id**, **-check**, and **-start** arguments. With the **-daemon** *master* option, *condor\_off* will shut down all daemons including the *condor\_master*. Specification using the **-daemon** option will shut down only the specified daemon. When shutting down all daemons including the *condor\_master*, the **-exec** argument can be used to tell the master to run a configured *MASTER\_SHUTDOWN\_\* script before it exits. For security reasons of authentication and authorization, this command requires **ADMINISTRATOR** level of access. ## OPTIONS - **-help** Display usage information - **-version** Display version information - **-graceful** The default. If jobs are running, wait for up to the configured grace period for them to finish, then exit - **-fast** Quickly shutdown daemons, immediately evicting any running jobs. A minimum of the first two characters of this option must be specified, to distinguish it from the **-force-graceful** command. - **-peaceful** Wait indefinitely for jobs to finish - **-force-graceful** Force a graceful shutdown, even after issuing a **-peaceful** command. A minimum of the first two characters of this option must be specified, to distinguish it from the **-fast** command. - **-drain** Send a *condor\_drain* command with the *-exit-on-completion* option to all *condor\_startd* daemons that are managed by this master. Then wait for all *condor\_startd* daemons to exit before before shutting down other daemons. - **-reason** *"reason-string"* Use with **-drain** to set a **-reason** *"reason-string"* value for the *condor\_drain* command. - **-request-id** *id* Use with **-drain** to set a **-request-id** *id* value for the *condor\_drain* command. - **-check** *expr* Use with **-drain** to set a **-check** *expr* value for the *condor\_drain* command. - **-start** *expr* Use with **-drain** to set a **-start** *expr* value for the *condor\_drain* command. - **-annex** *name* Turn off master daemons in the specified annex. By default this will result in the corresponding instances shutting down. - **-debug\[:opts\]** Causes debugging information to be sent to **stderr**. The debug level can be set by specifying an optional *opts* value. Otherwise, the configuration variable *TOOL\_DEBUG* sets the debug level. - **-pool** *centralmanagerhostname\[:portnumber\]* Specify a pool by giving the central manager's host name and an optional port number - **-name** *hostname* Send the command to a machine identified by *hostname* - ***hostname*** Send the command to a machine identified by *hostname* - **-addr** *"\"* Send the command to a machine's master located at *"\"* - ***"\"*** Send the command to a machine located at *"\"* - **-constraint** *expression* Apply this command only to machines matching the given ClassAd *expression* - **-all** Send the command to all machines in the pool - **-master** Shutdown the *condor\_master* after shutting down all other daemons. - **-exec** *name* When used with **-master**, the *condor\_master* will run the program configured as *MASTER\_SHUTDOWN\_\* after shutting down all other daemons. - **-daemon** *daemonname* Send the command to the named daemon. Without this option, the command is sent to the *condor\_master* daemon. ## GRACEFUL VS. PEACEFUL VS FAST A "fast" shutdown will cause the requested daemon to exit. Jobs running under a startd that is shutdown fast will be evicted. Jobs running on a schedd that is shutdown fast will be left running for their job lease duration (default of 20 minutes). (That is, assuming the corresponding startd is not also being shut down). If that schedd restarts before the job lease expires, it will reconnect to these running jobs and continue to run them, as long as the schedd and startd are running. A "graceful" shutdown of a schedd is functionally the same as a "fast" shutdown of a schedd. A "graceful" shutdown of a startd that has jobs running under it causes the startd to wait for the jobs to exit of their own accord, up to the MaxJobRetirementTime. After the MaxJobRetirementTime, the startd will evict any remaining running jobs and exit. A "peaceful" shutdown of a startd or schedd will cause that daemon to wait indefinitely for all existing jobs to exit before shutting down. During this time, no new jobs will start. ## 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 -daemon 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 ``` ## AUTHOR HTCondor Team ## COPYRIGHT 1990-2024, Center for High Throughput Computing, Computer Sciences Department, University of Wisconsin-Madison, Madison, WI, US.
