Re: [HTCondor-users] condor_off broken?

[Pek Daniel <pekdaniel@xxxxxxxxx>]

So now I have some more information:

condor_off command and friends won't work if the hostname is set to condorworker02 on the machine. It has to be set to condorworker02.domain.tld. 

The question: why is that?

OK, the problem a bit more detailed:

I'm using this version:

[root@lxbrb1815 ~]# condor_version

$CondorVersion: 8.1.2 Oct 19 2013 BuildID: 189797 $

$CondorPlatform: x86_64_RedHat5 $

Here's a snippet from condor_status -master output:

[root@condormaster1 ~]# condor_status -master

Name                

condormaster1       

condormaster2       

condorworker02      

lxbrb1815.domain.tld   

...

I have physical nodes and VMs as startd nodes. Physical nodes have more than one core, so more than one jobslots, while VMs have only one core.

Here's a snippet from condor_status -startd | head:

Name               OpSys      Arch   State     Activity LoadAv Mem   ActvtyTime

condorworker02     LINUX      X86_64 Claimed   Busy      0.000  490  0+00:03:13

slot1@xxxxxxxxxxxx LINUX      X86_64 Unclaimed Idle      0.060 1991  0+00:11:51

slot2@xxxxxxxxxxxx LINUX      X86_64 Unclaimed Idle      0.000 1991  0+00:12:13

...

As you can see, condorworker02 is a VM, while lxbrb1815.domain.tld is a physical node with a lot of cores. And that's the only difference. The config file is exactly the same for both cases, and the condor version as well.

Now, my questions:

- Why I see the slotID@xxxxxxxxxxxxxxxxxxxxxx in case of physical nodes and just the hostname in case of VMs?

- Why can't I query the status of a VM but it's working in case of a physical node:

[root@condormaster1 ~]# condor_status -startd lxbrb1815

[root@condormaster1 ~]# condor_status -startd condorworker02.domain.tld

[root@condormaster1 ~]# 

- Why can't I send condor_off command to VMs but it's working fine in case of physical nodes:

[root@condormaster1 ~]# condor_off -startd lxbrb1815

Sent "Kill-Daemon" command for "startd" to master lxbrb1815.domain.tld

[root@condormaster1 ~]# condor_off -startd condorworker02

Can't find address for master condorworker02.domain.tld

Perhaps you need to query another pool.

Thanks,

Daniel

Hmmm.  What does "condor_status -master" have to say?
