### Scheduling

This method of monitoring consumption, which is currently available only for `emptyDir` volumes, is faster and more accurate than the old method of walking the filesystem tree. Note that it does not enforce limits, it only monitors consumption. To utilize this functionality, set the feature gate `LocalStorageCapacityIsolationFSQuotaMonitoring=true`. For ext4fs filesystems, create the filesystem with `mkfs.ext4 -O project <block_device>` and run `tune2fs -Q prjquota `block device`; XFS filesystems need...

  This feature is in alpha. ([#122887](https://github.com/kubernetes/kubernetes/pull/122887), [@jpbetz](https://github.com/jpbetz))
