• [DOC OCP] Warn"kafka" must be used as the KafkaNodePool name when migrating to KafkaNodePool
  • There is nothing wrong with "Migrating existing Kafka clusters to use Kafka node pools" procedure(1) as the way to migrate to KafkaNodePool. However, if the procedure fails, at first glance data will be lost from the Kafka cluster because different new PVCs/PVs will be used.
  • "warning" or "important" should be stated, including the following intentions.
    • "kafka" must be used for KafkaNodePool name
    • The existing Kafka resource name(i.e. cluster-name) must be set to"strimzi.io/cluster" label.
    • If the above is not set correctly, each Kafka broker will not launch using the same PVCs/PVs as before after migrating to the KafkaNodePool, and the previous data will not be available properly.
