In general, Condor runs as user "condor" with homedirectory "/home/condor". And glideinWMS factory runs as "gfactory" with home directory "/home/gfactory".

Both the development ad production version of CRAB server submit to the same glideinWMS. I.e., we do not operate a development version of glideinWMS at this point for STEP09.

In the following, we go through one piece of hardware after the other and note some useful commands to figure out what's going on.


which condor_q

This will list all jobs presently known to the schedd on glidein-2. As glidein-2 is where the Crab server lives, this means it lists all the jobs that the Crab server has pushed into glideinWMS, and are not yet completed. A typical line looks like this:

8733.0   uscms2294       5/25 13:56   0+00:00:00 I  0   0.0  CMSSW.sh 119      
The first is the condor job Id. You can use that to get all the gory details about this job by doing:
condor_q -long 8733.0 >& junk.log
I redirected it into a file here because you will most likely want to look at this at your leisure, and carefully. There are a few particularly useful pieces of information in this long listing:
NumJobStarts = 0
NumRestarts = 0
If this isn't 0 or 1 then the glidein executing the job probably failed at that site once, and the job got rescheduled. This is a sign that either the site, or the glideinWMS is having trouble.

Other Details for STEP09
