Re: [HTCondor-users] Condor is still writing temp data to /var/opt/condor

["Mobley, Nate (Millennium)" <nmobley@xxxxxxxxxxxxxx>]

This is great news, now I think I know exactly what's causing the data to still go to "/var/opt/condor". My challenge now is how to change the config file on each compute node...I've never logged into them before. I'm having trouble determining what their IP addresses are, or else I think I could SSH into them with putty and modify the config files. I assume the " condor_config_val -v -startd -name compute-0-0.local EXECUTE" will show me the IP addresses, so I'll start there. Thank you all for your time.

Yes, there is a separate config for each node.  Also, daemons will only see changes to the config when you condor_reconfig (or restart) them.

The - before the name of your compute node is messing things up. you want this command.

condor_config_val -v -startd -name compute-0-0.local EXECUTE

not this

condor_config_val -v -startd -compute-0-0.local EXECUTE

The -startd and -name <name> arguments tell condor_config_val to ask the condor_startd daemon what its current config is.   This will be what the config files on that node contained at the time the condor_startd was last started or reconfiged - which might be older than what the config files say now.

Thanks again Todd. So when I ran " condor_config_val -v execute" it did show me the file I was expecting. But I got to thinking after that, is there a separate config file for each node?

I'm unfamiliar with what the config knob is, could you explain that a little more? I did run " condor_config_val -v -startd -compute-0-0.local" (where compute-0-0.local is the name of one of my compute nodes) and the error I received was "Can't connect to startd on head1.domainname.com <192.***.***.*: *****>" (domainname instead of my actual domain name)

Meant this line to be

condor_config_val -v -startd -name slot1@xxxxxxxxxxxxxxx LOCAL_DIR

Todd
