# ClusterVolumeSpec ## Properties Name | Type | Description | Notes ------------ | ------------- | ------------- | ------------- **group** | Option<**String**> | Group defines the volume group of this volume. Volumes belonging to the same group can be referred to by group name when creating Services. Referring to a volume by group instructs Swarm to treat volumes in that group interchangeably for the purpose of scheduling. Volumes with an empty string for a group technically all belong to the same, emptystring group. | [optional] **access_mode** | Option<[**crate::models::ClusterVolumeSpecAccessMode**](ClusterVolumeSpec_AccessMode.md)> | | [optional] [[Back to Model list]](../README.md#documentation-for-models) [[Back to API list]](../README.md#documentation-for-api-endpoints) [[Back to README]](../README.md)
