Hi,

 

Some of my STARTD/SCHEED nodes don’t show up in the condor_status list.

This probably has something to do with the fact that these nodes belong to a different network.

1) Do I have to use the flocking mechanism in order add such an “external node” (see setup below)?

2) If I do not have to use the flocking mechanism then how do I track down the error? I’ve already checked all the logs (on both the invisible nodes as well as on the collector) but I can’t find anything clue.

 

 

This is how my pool is set up:

 

FOO network:

 

Collector/Negotiator:

condor.FOO.my.com (Debian 6)

 

“Internal” Startd/Scheed nodes:

start1.FOO.my.com (CentOS 6)  <- LISTED

start2.FOO.my.com (Windows 7) <- LISTED

 

BAR network:

 

“External” Startd/Scheed node:

start3.BAR.my.com (OpenSuse 13) <- NOT LISTED

start4.BAR.my.com (Windows 7)   <- NOT LISTED

 

 

 

Collector/Negotiator condor_config.local:

 

CONDOR_HOST = condor.FOO.my.com

DAEMON_LIST = MASTER, COLLECTOR, NEGOTIATOR

ALLOW_WRITE = *.FOO.my.com, *.BAR.my.com

 

SGE_GAHP      = $(GLITE_LOCATION)/bin/batch_gahp

GLIDEIN_SITES = *.FOO.my.com

 

HOSTALLOW_WRITE = $(HOSTALLOW_WRITE), $(GLIDEIN_SITES)

Since HOSTALLOW_WRITE, if used, overrides ALLOW_WRITE, this is the relevant line to look at.

I think you want:

HOSTALLOW_WRITE = $(HOSTALLOW_WRITE), $(GLIDEIN_SITES), *.BAR.my.com

?

If it's a simple copy/paste error, a few other ideas:

- Look at /var/log/condor/CollectorLog and look for PERMISSION DENIED lines.  They often give a good hint as to what went wrong.

- Restart the collector with D_SECURITY set for COLLECTOR_DEBUG.  This will greatly increase the verbosity but also give more hints as to what is gone wrong.

Finally, this is not a particularly secure setup - host-based security may not be secure as you would want, especially as you start to involve multiple networks.  I can't find any good links at the moment, but maybe others could chime in?
