Hi <@U04QAUP4DC2>,

There should be only one PDB `signoz-clickhouse-cluster`  in `signoz-0.19.x` chart.

Ref: <https://github.com/Altinity/clickhouse-operator/blob/release-0.21.2/pkg/model/creator.go#L838>

Have you followed all steps from v0.23 migration docs before upgrading?

The PDB errors we experienced were before upgrading to signoz-0.19.1. Glad to hear this should be resolved. Will monitor.

I see. Do let us know how it goes with the K8s version upgrade as well.

We managed to work through the k8s upgrade, just required additional effort to work through it.

Thanks!
