func (m *VolumeQoSManager) ConfigureQoSForLocalVolumeReplica(replica *apisv1alpha1.LocalVolumeReplica) error

ConfigureQoSForLocalVolumeReplica configures the QoS for a volume.

func (*VolumeQoSManager) IsFilesystemInitialized

func (m *VolumeQoSManager) IsFilesystemInitialized(replica *apisv1alpha1.LocalVolumeReplica) bool

IsFilesystemInitialized checks if the filesystem is initialized. It must be called before configuring QoS for a volume. If the filesystem is not initialized, we should skip volume QoS configuration in order to void the mkfs process hangs, See #958 for details.
