Is it possible to resize disk on individual brokers?

I'm not having much luck finding current information on how strimzi supports volume resizing. Based on this blog post from 2019, it appears that the operator supports EBS resizing if it's enabled on the storageclass.

I have the following configured for storage on my cluster:

    storage:
      type: jbod
      volumes:
      - id: 0
        type: persistent-claim
        size: 1500Gi
        deleteClaim: true

I have 9 brokers currently. We have some large single-partitioned topics that are making a few of the brokers more full than others.

Is it possible to add storage to particular brokers or do I have to update all of them?

You cannot configure the storage size per broker. But you can create different KafkaNodePools with different types of brokers. For example one with 3 brokers with small storage and another one with 3 brokers with large storage (If you take it to extreme, you can have many node pools each with 1 broker). The only issue is that Kafka does not really support any advanced scheduling of the topics to different brokers. So you pretty much have to manually make sure that the topics are on the correct brokers.
