Troubleshooting Information

This section describes how to resolve some of the known issues in CDL configuration. Before proceeding with troubleshooting CDL configurations, consider the following:

  • system-id is unique across the site.

  • cluster-id (datastore id) is unique within the site.

  • You cannot change the replica of Index after deploying the CDL. To change the replica:

    1. Set the system mode to "shutdown".

    2. Change the replica.

    3. Set the system mode to "running".

  • The replica of Endpoint, Index, Slot and Kafka pods must be less than or equal to the number of k8 nodes with the following label and value:

    • Label: smi.cisco.com/node-type.

    • Value: Value of cdl/node-type. In a multi-node setup, the default value is session.

  • The replica of Zookeeper and ETCD pods must be less than or equal to the number of k8 nodes with the following label and value:

    • Label: smi.cisco.com/node-type.

    • Value: oam.

  • In a Geo-replication setup (across the sites cluster-id), the replicas, and maps of the Index and Slot pods must be identical. Otherwise data replication may fail.
