According to what i read in some presentations, and the most
relevant, this topic on the list "What makes a node execute node or
not a execute node", i just have to put on the DAEMON_LIST the
STARTD, and restart condor_master, so if the central-manager (the
machine itself) is correctly pointed on condor_config, it will
communicate with the collector, and become an execute node.
So, i did it, but i couldn't see the central manager on
condor_status list, am i missing something?
Before I answer your question...
In general, you have to be really careful about running jobs on your
central manager. A lot of people set up Condor with host permissions,
which means that to have administrator privileges you only need to be
on a certain computer. (There are stronger authentication methods
available, but people often use host permissions anyway.) A common
configuration is to say "If you are on the central manager, you have
administrator privileges for the whole pool.) If you do this, jobs
that run on the central manager have elevated privileges with respect
If you're running Condor just to try it out, or if you only have
trusted users, maybe you don't care. But I think it's pointing out so
that people don't make a mistake that can affect their security.
On to your question...
1) Look in the MasterLog on the central manager: did the master
restart? Did it start the condor_startd?
2) Do you see a condor_startd process?
3) Do you see any errors in the StartLog (the log file for the
4) Do you see any errors in the CollectorLog? This is where the
condor_startd sends information to let the pool know that it exists.
