Pod has unbound immediate PersistentVolumeClaims

[jaispirit (Alexander Goettert)]

Hello,

I'm trying to deploy ECK quickstart into my Cluster.

Unfortunately I'm getting the message 'pod has unbound immediate PersistentVolumeClaims (repeated 2 times)'. Why doesn't the claim access the volume?

I changed today the pv from a local-storage to an nfs pv:

The pod still has unbound immediate PersistentVolumeClaims (repeated 2 times):
