Synopsis

condor_off[-help -version]

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

Description

condor_offshuts 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_offwithout any arguments will shut down all daemons except condor_master. The condor_mastercan 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_oncommand.

With the -daemon masteroption, condor_offwill shut down all daemons including the condor_master. Specification using the -daemonoption will shut down only the specified daemon.

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