Resolving Kubernetes Pod has unbound PersistentVolumeClaims Error

Hi guys, I found a problem with volume configuration error during kubernetes container initialization. I tried a lot of way to solve this problem such as creating longhorn provisioner and local path and node but these ways didn't resolve problem on initialization. I used nfs-server-provisioner catalog app for helm and i see a new storage class named nfs. I remove my another storage classes to force new apps to use this storage class. This worked like a charm! Now i can install all of catalog apps without any persistence and volume based problem.
