CONDOR_RESTART(1)

NAME
condor_restart - HTCondor Manual

Restart a set of HTCondor daemons

SYNOPSIS

condor_restart [-help | -version ]

condor_restart [-debug[:opts]] ] [-graceful | -fast | -peaceful | -drain ] [-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_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.

When restarting 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 restarts.

When the -drain option is chosen, draining options can be specified by using the optional -reason, -request-id, -check, and -start arguments.

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

OPTIONS

-help
    Display usage information

-version
    Display version information

-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.

-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

-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 restarting.

-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.

-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
    Restart the condor_master after shutting down all other daemons. This will have the effect of restarting all of the 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.

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
