The CSI external-attacher coordinates with CSI volume driver and updates the volumeattachment status when the attach operation is complete. If the value is specified to false, the attach operation will be skipped. Otherwise the attach operation will be called. This field is immutable. fsGroupPolicystring fsGroupPolicy defines if the underlying volume supports changing ownership and permission of the volume before being mounted. Refer to the specific FSGroupPolicy values for additional details. This field was immutable in Kubernetes \\ nodeAllocatableUpdatePeriodSecondsinteger nodeAllocatableUpdatePeriodSeconds specifies the interval between periodic updates of the CSINode allocatable capacity for this driver. When set, both periodic updates and updates triggered by capacity-related failures are enabled. If not set, no updates occur (neither periodic nor upon detecting capacity-related failures), and the allocatable.count remains static. The minimum allowed value for this field is 10 seconds. This feature requires the MutableCSINodeAllocatableCount feature gate to be enabled. This field is mutable. podInfoOnMountboolean podInfoOnMount indicates this CSI volume driver requires additional pod information (like podName, podUID, etc.) during mount operations, if set to true. If set to false, pod information will not be passed on mount. Default is false. The CSI driver specifies podInfoOnMount as part of driver deployment. If true, Kubelet will pass pod information as VolumeContext in the CSI NodePublishVolume() calls. The CSI driver is responsible for parsing and validating the information passed in as VolumeContext. The following VolumeContext will be passed if podInfoOnMount is set to true. This list might grow, but the prefix will be used. …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
