       Shutdown HTCondor daemons

SYNOPSIS

       condor_off [-help | -version ]

       condor_off  [-graceful  |  -fast  | -peaceful | -force-graceful | -drain ] [-annex name] [-debug[:opts] ]
       [-pool centralmanagerhostname[:portnumber]] [ -name  hostname  |  hostname  |  -addr  "<a.b.c.d:port>"  |
       "<a.b.c.d:port>"  |  -constraint expression | -all ] [-daemon daemonname | -master] [-exec name] [-reason
       "reason-string"] [-request-id id] [-check expr] [-start expr]

DESCRIPTION

       condor_off shuts down a set of the HTCondor daemons running on  a  set  of  one  or  more  machines.   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_<Name> 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 "<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

          -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_<Name> 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
