Troubleshoot a local cluster

Why did the advanced cluster fail to start?: To troubleshoot why the advanced cluster failed to start, examine the
ccs-operation.log
file in the following directory on the Secure Agent machine:
<Secure Agent installation directory>/apps/At_Scale_Server/<version>/ccs_home/

The ccs-operation.log couldn't help me resolve the issue. Where else can I look?: If there isn't enough information in the
ccs-operation.log
file to help you resolve the issue, try reviewing the
cluster-operation.log
file that is dedicated to the instance of the advanced cluster.
When an external command set runs, the ccs-operation log displays the path to the cluster-operation logs. For example:
2020-06-15 21:22:36.094 [reqid:] [T:000057] INFO : c.i.c.s.c.ClusterComputingService [CCS_10400] Starting to run command set [<command set>] which contains the following commands: [ <commands> ; ].
You can find the execution log in the following location:
/data2/home/cldagnt/SystemAgent/apps/At_Scale_Server/35.0.1.1/ccs_home/3xukm9iqp5zeahyrb7rqoz.k8s.local/infa/cluster-operation.log
The specified folder contains all cluster-operation logs that belong to the instance of the cluster. You can use the logs to view the full stdout and stderr output streams of the command set.

Why are my jobs not being processed on the local cluster?: The OS firewall might be preventing the worker nodes from sending the jobs to the local cluster for processing.

Check if the firewall is running using this command:
sudo firewall-cmd –state
If the output of this command mentions "running", then the firewall is active.

Disable the OS firewall daemon with this command:
sudo systemctl disable firewalld
