Description

17       condor_offshuts down a set of the HTCondor daemons running on a set  of
18       one  or more machines. It does this cleanly so that checkpointable jobs
19       may gracefully exit with minimal loss of work.
20
21       The command condor_offwithout any arguments will shut down all  daemons
22       except  condor_master,  unless -annex nameis specified. The condor_mas‐
23       tercan then handle both local and remote requests to restart the  other
24       HTCondor  daemons if need be. To restart HTCondor running on a machine,
25       see the condor_oncommand.
26
27       With the -daemon masteroption, condor_offwill  shut  down  all  daemons
28       including the condor_master. Specification using the -daemonoption will
29       shut down only the specified daemon.
30
31       For security reasons of authentication and authorization, this  command
32       requires ADMINISTRATORlevel of access.

Examples

145       To shut down all daemons (other than condor_master) on the local host:
146
147       % condor_off
148
149       To shut down only the condor_collectoron three named machines:
150
151       % condor_off  cinnamon cloves vanilla -daemon collector
152
153       To  shut  down  daemons  within a pool of machines other than the local
154       pool, use the -pooloption. The argument is the name of the central man‐
155       ager  for the pool. Note that one or more machines within the pool must
156       be specified as the targets for the command. This  command  shuts  down
157       all  daemons  except  the  condor_masteron  the  single  machine  named
158       cae17within the pool of machines  that  has  condor.cae.wisc.eduas  its
159       central manager:
160
161       % condor_off  -pool condor.cae.wisc.edu -name cae17
