Rook: Rook not creating PVC and errors

[alialshamali]

Hi,

I am sure I am doing something wrong, but can't figure it out. I create everything is up from a operator and cluster perspective(double confirmed the cluster is OK) but when I am creating PVC using mysql example, and I am not able to. I am just get Pending in pvc get:
mysql-pv-claim Pending collectiveblock 19s

When I describe it I get the following:

Normal   Provisioning          6s (x5 over 1m)   rook.io/block rook-operator-7cf8b7b766-tgm58 ae7b64f6-21da-11e8-b0f7-9ad3f40997ae  External provisioner is provisioning volume for claim "default/mysql-pv-claim"

I am checking the kubelet logs of where the pod is being create I see the following error:

2815 desired_state_of_world_populator.go:273] Error processing volume "mysql-persistent-storage" for pod "wordpress-mysql-557ffc4f69-8t74c_default(3d13715d-21e0-11e8-8276-0cc47ade9b1e)": error processing PVC "default"/"mysql-pv-claim": PVC default/mysql-pv-claim has non-bound phase ("Pending") or empty pvc.Spec.VolumeName ("")

The following is the Pool and Storageclass configurion:

apiVersion: rook.io/v1alpha1
kind: Pool
metadata:
  name: collectivepool
  namespace: warehouse
spec:
  replicated:
    size: 2
  erasureCoded:
    dataChunks: 2
    codingChunks: 1
  crushRoot: default
---
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: collectiveblock
provisioner: rook.io/block
parameters:
  pool: collectivepool
  clusterName: warehouse
  clusterNamespace: warehouse

And this PVC config I am using same as the example just renamed the storageclassname:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pv-claim
  labels:
    app: wordpress
spec:
  storageClassName: collectiveblock
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 20Gi

Thanks

Thanks I am going to go ahead and close the case. I think I figured out what is happening, I will reopen with the correct format if I can't resolve it.

Excellent Project huge fan!
