condor_off

Shutdown HTCondor daemons

Synopsis

condor_off [-help | -version]

condor_off [-graceful | -fast | -peaceful | -force-graceful] [-annex  name] [-debug] [-pool  centralmanagerhostname[:portnumber]] [ -name hostname | hostname | -addr "<a.b.c.d:port>" | "<a.b.c.d:port>" | -constraint expression | -all ] [-daemon  daemonname]

Description

condor_off shuts down a set of the HTCondor 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, 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.

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.

For security reasons of authentication and authorization, this command requires ADMINISTRATOR level of access.

Options

-help

Display usage information

-version

Display version information

-graceful

Gracefully shutdown daemons (the default)

-fast

Quickly shutdown daemons. 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.

-annex name

Turn off master daemons in the specified annex. By default this will result in the corresponding instances shutting down.

-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 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 "<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>"

-constraint expression

Apply this command only to machines matching the given ClassAd expression

-all

Send the command to all machines in the pool

-daemon daemonname

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:

To shut down only the condor_collector on three named machines:

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:
