Hey <@U03EXU0EJ74>!

Can you share more  details about your k8s cluster?

I was able to create a SigNoz cluster with custom PVC using `clickhouse.persistence.existingClaim` helm configuration without any problem.

I used the following PVC in EKS.
```apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-claim-2
spec:
  storageClassName: gp2
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 21Gi```

And this is the Helm command that I used:
```helm upgrade --install --namespace platform --create-namespace my-release  signoz/signoz --set clickhouse.persistence.existingClaim=pvc-claim-2```
