Hi Condor Folks!
I've submitted this message last Friday and I still didn't get any reply.
Any tip will be very appreciated!
Thanks in advance.
Regards,
Fabiano.

Thanks a lot for your tips David!
In fact, I decided to clean up all jobs in idle state and test again.
I started up pool with 4 nodes:
=======================================================
[globus@cruzi log]$ condor_status
Name OpSys Arch State Activity LoadAv Mem
ActvtyTime
crithidia LINUX INTEL Unclaimed Idle 0.000
503 0+00:18:39
cruzi LINUX INTEL Unclaimed Idle 0.030 501
0+00:25:05
genome LINUX INTEL Unclaimed Idle 0.000 1519
0+00:27:22
vivax LINUX INTEL Unclaimed Idle 0.000 757
0+00:20:07
Total Owner Claimed Unclaimed Matched
Preempting Backfill
INTEL/LINUX 4 0 0 4 0
0 0
Total 4 0 0 4 0
0 0
=======================================================
After submit simple test
(http://www.cs.wisc.edu/condor/tutorials/intl-grid-school-3/submit_first.html)
in vivax node, I ran "condor_q -better-analyze" and I got the following:
=======================================================
[globus@vivax testcondor]$ condor_q -better-analyze
-- Submitter: vivax.wwwwww.www : <xxx.x.x.xxx:xxxx> : vivax.wwwwww.www
---
002.000: Run analysis summary. Of 4 machines,
3 are rejected by your job's requirements
0 reject your job because of their own requirements
0 match but are serving users with a better priority in the pool
1 match but reject the job for unknown reasons
0 match but will not currently preempt their existing job
0 are available to run your job
The Requirements expression for your job is:
( target.Arch == "INTEL" ) && ( target.OpSys == "LINUX" ) &&
( target.Disk >= DiskUsage ) && ( ( target.Memory * 1024 ) >=
ImageSize ) &&
( TARGET.FileSystemDomain == MY.FileSystemDomain )
Condition Machines Matched Suggestion
--------- ---------------- ----------
1 ( TARGET.FileSystemDomain == "vivax.wwwwww.www" )
1
2 ( target.Arch == "INTEL" ) 4
3 ( target.OpSys == "LINUX" ) 4
4 ( target.Disk >= 5 ) 4
5 ( ( 1024 * target.Memory ) >= 5 ) 4
=======================================================
This means that I need to setup TARGET.FileSystemDomain to allow
others nodes in pool beside submitter.
My question is: how to do that? My submit file doesn't contain this
property - I've followed all steps from URL above.
This pool doesn't run over NFS - local config files of all nodes
point to vivax as central manager. Note that I don't have a condor
user either - just globus user, but it was added as super user in
config file variable of all nodes ($CONDOR_HOME/etc/condor_config).
Thanks in advance for your help.
Regards,
Fabiano.

To find out why jobs are not running well, you'll need to read
through
the logfiles for the submit node and the execute node or nodes.
You can
also specify a logfile in your submit description for the job.
There's
no quick and easy answer to this. It will depend on why the job is
performing poorly. It may be that your machines are having
keyboard or
mouse activity that put them in the Owner state and interrupt
your jobs.
Look at the job log, the ShadowLog, and the StarterLog first. They
should indicate state transitions and possibly the reasons for them.

condor_off should work, but it has to be run by an authorized
user, such
as root or condor, or from a user on a machine where all users are
allowed admin rights.
