Hi All, I am facing one issue while deploying pinot on K8s. Can someone help me out? I am trying to install pinot on k8's cluster which is the latest helm released chart:

0.9.3

- https://github.com/apache/pinot/blob/master/kubernetes/helm/README.md The only change I have made is the

nodeSelector

in values.yaml file. I am getting errors while using this command for installing helm in K8's cluster

helm install pinot . -f values.yaml -n pinot --set cluster.name=pinot --set server.replicaCount=2

Here are the zookeeper logs:

The disk space I am having is 25GB.

@Mayank Could you have a look pls?

I see “no space left on device” in your log

@Mayank I have increased the space to 50 GB. Still, it's the same issue.

Is that 50 GB available for /data/log?

The issue is fixed, it was because of PV

storageClass

. The name was not correct. Once we have removed the existing PV and re-created it the issue was resolved.

Thanks for confirming
