condor_restart

Restart a set of Condor daemons

Synopsis

condor_restart [-help | -version]

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]

Description

condor_restart restarts a set of Condor 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.

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_master daemon.

Exit Status

condor_restart will 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_master and all its children on the local host:

% condor_restart

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
