n_ : Fixes an issue where PVC was bound to invalid PV created using incorrect values provided in PVC/Storageclass.
Need to find a better word for "invalid" to qualify this PV.

made it unusable.
Fixes an issue where PVC was bound to unusable PV created using incorrect values provided in PVC/Storageclass.
The controller does not check whether the volume has been created or not and return successful. Which in turn binds the pvc to the pv. The PVC should not bound until corresponding zfs volume has been created. Now controller will check the ZFSVolume CR state to be "Ready" before returning successful. The CSI will retry the CreateVolume request when it will get a error reply and when the ZFS node agent creates the ZFS volume and sets the ZFSVolume CR state to be "Ready", the controller will return success for the CreateVolume Request and then PVC will be bound.

PVC will not bound if there is wrong parameters/poolname in the storageclass, the ZFSVolume CR will be still created and will remain in Pending State, deletion of the PVC will delete PVC and since PVC is not bound, ZFS-LocalPV driver will not get the delete call and will leave the ZFSVolume CR hanging there. Reverting the behavior introduced in openebs#121, Now PVC will be bound but still ZFSVolume will be in Pending state until the volume is created. Signed-off-by: Pawan <pawan@mayadata.io>

fixes: #111
Signed-off-by: Pawan pawan@mayadata.io
Why is this PR required? What issue does it fix?:
The controller does not check whether the volume has been created or not
and return successful. Which in turn binds the pvc to the pv.
What this PR does?:
The PVC should not bound until corresponding zfs volume has been created.
Now controller will check the ZFSVolume CR state to be "Ready" before returning
successful. The CSI will retry the CreateVolume request when it will get
a error reply and when the ZFS node agent creates the ZFS volume and sets the
ZFSVolume CR state to be "Ready", the controller will return success for the
CreateVolume Request and then PVC will be bound.
