After deploying application using helm facing error pod has unbound immediate PersistentVolumeClaims attached with pvc

Question

I am trying to deploy a sample postgres on k8s cluster using helm. After deploying the application I ran kubectl get pods and then my application was in pending state because of this error "pod has unbound immediate PersistentVolumeClaims."

Please check the logs:

The issue is resolved I was not having storage in my cluster, so this issue got resolved by installing longhorn — Sushant Jha, May 12 '21 at 13:07

This means your pods are requesting more PVC storage than actual it's present. makes sure you assign PVC correct to pods.

You can check the PVC

kubectl get pvc

In kubectl get pvc it shows status as pending, there is a lot of space, what else can be the issue? – Sushant Jha Sep 29 '20 at 11:29
