condor_ off

Shutdown condor daemons

Synopsis

condor_ off [-help | -version]

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 3.6.1 on page for further explanation.

Options

-help: Display usage information
-version: Display version information
-graceful: Gracefully shutdown daemons (the default)
-fast: Quickly shutdown daemons
-peaceful: Wait indefinitely for jobs to finish
-debug: Causes debugging information to be sent to stderr based on the value of the configuration variable TOOL_DEBUG
-pool centralmanagerhostname[:portnumber]: Specify a pool by giving the central manager's hostname 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 "<a.b.c.d:port>": Send the command to a machine's master located at "<a.b.c.d:port>"
"<a.b.c.d:port>": Send the command to a machine located at "<a.b.c.d:port>"
-all: Send the command to all machines in the pool
-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
