[HTCondor-users] condor_status Error: Communication error

["Zeng, Xinjie (zengxe)" <xinjie.zeng@xxxxxxxxxxxxxx>]

Dear htcondor users,

I am new to HTcondor and I try to set up the condor pool for my two computers. I installed htcondor from the respository.

For my central manager machine, my configuration is like:

CONDOR_HOST = 172.21.85.199

COLLECTOR_HOST = $(CONDOR_HOST):9618

DAEMON_LIST = COLLECTOR, MASTER, NEGOTIATOR, SCHEDD, STARTD

ALLOW_WRITE = *

ALLOW_READ = *

CONDOR_IDS=0.0

The condor version is

$CondorVersion: 8.8.9 May 06 2020 BuildID: 503068 PackageID: 8.8.9-1 $

$CondorPlatform: x86_64_CentOS7 $

 

For the submit & execute machine, my configuration is :

CONDOR_HOST = 172.21.85.199

DAEMON_LIST = MASTER, SCHEDD, STARTD

ALLOW_WRITE = *

ALLOW_READ = *

CONDOR_IDS=0.0

The condor version is

$CondorVersion: 8.8.9 May 06 2020 BuildID: 503068 PackageID: 8.8.9-1 $

$CondorPlatform: x86_64_CentOS7 $

 

I run condor_q, and condor_master, they work fine. However, when I run condor_status in both computers, I got:

condor_status

Error: communication error

 

When I look into MasterLog in the central machine, I found:

05/31/20 18:57:36 ERROR "Can't get lock on "/var/lock/condor/InstanceLock"" at line 1393 in file /var/lib/condor/execute/slot1/dir_23498/userdir/.tmpXxBBdB/BUILD/condor-8.8.9/src/condor_master.V6/master.cpp

05/31/20 18:57:58 SharedPortEndpoint: failed to open /var/lock/condor/shared_port_ad: No such file or directory

05/31/20 18:57:58 SharedPortEndpoint: did not successfully find SharedPortServer address. Will retry in 60s.

And in the Collector Log I found:

05/31/20 18:41:45 ERROR "Unable to determine my own address, aborting rather than hang. You may need to make sure the shared port daemon is running first." at line 1687 in file /var/lib/condor/execute/slot1/dir_23498/userdir/.tmpXxBBdB/BUILD/condor-8.8.9/src/condor_collector.V6/collector.cpp

 

I searched a lot and tried a lot but couldnât fix this error. Does anyone has experience about this? Any advises are appreciated!

Thank you very muchï

 

Warm Regards,

Xinjie Zeng
