#### Volume Plugins
* [stable] Volume plugin for StorageOS provides highly-available cluster-wide persistent volumes from local or attached node storage. See [Persistent Volumes - StorageOS](https://kubernetes.io/docs/concepts/storage/persistent-volumes/#storageos) and [Storage Volumes - StorageOS](https://kubernetes.io/docs/concepts/storage/volumes/#storageos).
