The FIXED_LENGTH value indicates that data ranges are returned in fixed size blocks.

The VARIABLE_LENGTH value indicates that data ranges are returned in potentially variable sized extents.

Plugins supporting volume cloning at the storage level MAY report this capability.

Currently the only way to consume a snapshot is to create a volume from it.

See VolumeExpansion for details.

Indicates the SP supports the ControllerGetVolume RPC.

Indicates that Node service supports mounting volumes with provided volume group identifier during node stage or node publish RPC calls.

CONTROLLER_SERVICE indicates that the Plugin provides RPCs for the ControllerService.

GROUP_CONTROLLER_SERVICE indicates that the Plugin provides RPCs for operating on groups of volumes.

SNAPSHOT_METADATA_SERVICE indicates that the Plugin provides RPCs to retrieve metadata on the allocated blocks of a single snapshot, or the changed blocks between a pair of snapshots of the same block volume.

VOLUME_ACCESSIBILITY_CONSTRAINTS indicates that the volumes for this plugin MAY NOT be equally accessible by all nodes in the cluster.

OFFLINE indicates that volumes currently published and available on a node SHALL NOT be expanded via ControllerExpandVolume.
