+{{< feature-state for_k8s_version="v1.22" state="alpha" >}}
+
+In Kubernetes v1.22 a fourth access mode was introduced. Note that this access mode is only supported for CSI volumes:
+
+* ReadWriteOncePod -- the volume can be mounted as read-write by a single pod
+
+In the CLI, this access mode is abbreviated to RWOP.
+
 > __Important!__ A volume can only be mounted using one access mode at a time, even if it supports many.  For example, a GCEPersistentDisk can be mounted as ReadWriteOnce by a single node or ReadOnlyMany by many nodes, but not at the same time.
