Description

       condor_restartrestarts a set of HTCondor daemons on a set of machines. The daemons will  be  put  into  a
       consistent state, killed, and then invoked anew.

       If,  for  example,  the  condor_masterneeds to be restarted again with a fresh state, this is the command
       that should be used to do so. If the DAEMON_LISTvariable in the configuration file has been changed, this
       command is used to restart the condor_masterin order to see this  change.  The  condor_reconfigurecommand
       cannot be used in the case where the DAEMON_LISTexpression changes.

       The  command  condor_restartwith  no arguments or with the -daemon masteroption will safely shut down all
       running jobs and all submitted jobs from the machine(s) being restarted, then shut  down  all  the  child
       daemons  of  the  condor_master,  and  then  restart  the  condor_master.  This,  in turn, will allow the
       condor_masterto start up other daemons as specified in the DAEMON_LISTconfiguration file entry.

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

Options

       -help

          Display usage information

       -version

          Display version information

       -debug

          Causes  debugging  information  to be sent to stderr, based on the value of the configuration variable
          TOOL_DEBUG.

       -graceful

          Gracefully shutdown daemons (the default) before restarting them

       -fast

          Quickly shutdown daemons before restarting them

       -peaceful

          Wait indefinitely for jobs to finish before shutting down daemons, prior to restarting them

       -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_masterdaemon.

Exit Status

       condor_restartwill  exit  with a status value of 0 (zero) upon success, and it will exit with the value 1
       (one) upon failure.

Examples

       To restart the condor_masterand all its children on the local host:

       % condor_restart

       To restart only the condor_startdon a named machine:

       % condor_restart  -name bluejay -daemon startd

       To restart a machine within a pool other than the local pool, use the -pooloption. 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 restarts the single machine named cae17within  the
       pool of machines that has condor.cae.wisc.eduas its central manager:

       % condor_restart  -pool condor.cae.wisc.edu -name cae17
