Hyper-V Clustering - Cluster Storage

I have created a Hyper V failover Clustering between 2 nodes. 

On both nodes in C drive it created a folder ClusterStorage where i will store the Virtual Machine on. But i get an error that the user doesnt have access to the folder. 

Also noticed that the folder ClusterStorage has the security lock on it. 

Any ideas on how to give access to the administrator user?
