condor_restart [-debug] [-graceful -fast -peaceful] [-pool centralmanagerhostname[:portnumber]] [-name hostname hostname -addr "a.b.c.d:port" "a.b.c.d:port" -constraint expression -all ] [-daemon daemonname]
condor_restart restarts 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_master needs 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_master in order to see this change. The condor_reconfigure command cannot be used in the case where the DAEMON_LIST expression changes.
The command condor_restart with no arguments or with the -daemon master option 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_master to start up other daemons as specified in the DAEMON_LIST configuration file entry.
For security purposes (authentication and authorization), this command requires an administrator's level of access. See section 3.6.1 on page for further explanation.
condor_restart will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
To restart only the condor_startd on a named machine:
% condor_restart -name bluejay -daemon startd
To restart a machine within a pool 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 restarts the single machine named cae17 within the pool of machines that has condor.cae.wisc.edu as its central manager:
% condor_restart -pool condor.cae.wisc.edu -name cae17
