Hi team!! I notice when restarting clickhouse, the following events occur:

Pod "chi-signoz-clickhouse-cluster-0-0-0" matches multiple PodDisruptionBudgets. Chose "signoz-clickhouse-cluster" arbitrarily.

Pod "chi-signoz-clickhouse-cluster-0-0-0" matches multiple PodDisruptionBudgets. Chose "signoz-clickhouse" arbitrarily.

This also seemed to interfere with upgrading kubernetes:

(UpgradeFailed) Drain of aks-node did not complete: Evict blocked by conflicting disruption budgets on pod chi-signoz-clickhouse-cluster-0-0-0 on node aks-node: chi-signoz-clickho
use-cluster-0-0-0. See <http://aka.ms/aks/debugdrainfailures>

Hi @Al, 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!
