Hello,

I’m working with Zeebe about 1 year and recently I tried to increase the partitionCount , clusterSize and replicationFactor, from 1 to 3 in all theese fields.

But all the pods in the cluster haven’t the green healty status and also, have problems logged. I guess that the problem is about the partition because only the previous node have the partition set up.

  1. What did you expect to happen? What did happen?
    The brokers work correctly each other and have more partitions

  2. What environment are you running C8 on?
    I’m using GCP - GKE

  3. What version are you running?
    8.4.3

  4. Are all pods running
    All pods are running but only one is “healthy” by the Kube

When I create a new cluster works perfeclty. I guess that the problem is about the partitions.

Anyone have any idea?

You need to delete zeebe’s storage volume data and then restart zeebe.

but in this way, I’ll lost all the old data, right?

5

Yes, there is no better way.

okay, thanks. But I can resize the cluster size without problem?
