Synopsis

condor_restart[-help -version]

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

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_LIST variable 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_LIST expression 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_LIST configuration file entry.

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

-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

-constraint expression

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
