Disable persistent does not work

I try to create redis enterprise cluster with below declaration

apiVersion: "app.redislabs.com/v1"
kind: "RedisEnterpriseCluster"
metadata:
  name: "harbor-cluster"
spec:
  nodes: 3
  persistentSpec:
    enabled: false
  redisEnterpriseNodeResources:
    limits:
      cpu: 1000m
      memory: 1Gi
    requests:
      cpu: 1000m
      memory: 1Gi

But my problem is even I set presistentSpec to false, I see kubectl get pvc show redis try to claim pv and my bootstrapping of my pods is failed.

my question is how to resolve it?

Hi,

That seems very strange. Would you be able to run the log_collector.py script in order to generate a diagnostic package and open a Support Ticket with Redis so that we can take a look? Also, the memory requested (1Gi) is too small. The nodes will not work. We recommend at least 4Gi for testing. I think 3 Gi "might" work.

My problem is why

kubectl get pvc has result for redis?

If I run kubectl describe pvc redis-enterprise-storage-harbor-cluster-0 we can see below result

But as you can see I set presistentSpec enabled property to false.

I try to ask my question on SO

Where is log_collector.py?

Hi,

The script is here: https://github.com/RedisLabs/redis-enterprise-k8s-docs/tree/master/log_collector

Is it possible that you had previously created a Redis Enterprise Cluster with the same name before? I am thinking the PVC could be from a previous run. Can you check if the PVC is older than the REC by comparing their creation timestamp?

@laurentdroin thanks you correct
