- Fixed FibreChannel volume plugin corrupting filesystems on detach of multipath volumes. ([#97013](https://github.com/kubernetes/kubernetes/pull/97013), [@jsafrane](https://github.com/jsafrane)) [SIG Storage]

You can find a list of sample and production drivers in the [CSI Documentation](https://kubernetes.io/docs/concepts/storage/volumes/#csi).

SIG Storage also moves support for Block Volumes to beta (introduced as alpha in v1.9) and support for Topology Aware Volume Scheduling to stable (introduced as alpha in v1.9 and promoted to beta in 1.10).

### SIG UI

- Generic ephemeral volumes, a new alpha feature under the `GenericEphemeralVolume` feature gate, provide a more flexible alternative to `EmptyDir` volumes: as with `EmptyDir`, volumes are created and deleted for each pod automatically by Kubernetes. But because the normal provisioning process is used (`PersistentVolumeClaim`), storage can be provided by third-party storage vendors and all of the usual volume features work. Volumes don't need to be empty; for example,...

- StorageOS volume plugin updated to fix an issue where volume mount succeeds even if request to mount via StorageOS API fails. ([#69782](https://github.com/kubernetes/kubernetes/pull/69782), [@darkowlzz](https://github.com/darkowlzz))

These changes are reflected in the following Kubernetes enhancements:
([#625](https://github.com/kubernetes/enhancements/issues/625))

#### Additional Notable Feature Updates

the in-tree storage drivers indicate support for the `MetricsProvider` interface, but fail to configure this for BlockMode volumes. With a recent change, `Kubelet` will call `GetMetrics()` for BlockMode volumes, and the in-tree drivers that miss the support cause a Go panic. Now the in-tree storage drivers that support BlockMode volumes, will return the Capacity of the volume in the `GetMetrics()` call.

- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached, Kubernetes will make sure they are fully attached before they can be used by pods.
